[U-Boot] [PATCH 1/3] config.mk: move LDSCRIPT processing to the top-level Makefile
by Ilya Yanok 22 Jun '11

22 Jun '11

LDSCRIPT is used only from the top-level Makefile and only when the system is configured so we can move LDSCRIPT and CONFIG_SYS_LDSCRIPT related logic into the top level Makefile and under configured condition to avoid errors when building tools from unconfigured tree.

[U-Boot] [PATCH] ARM: drop unsupported 'trab' board
by Wolfgang Denk 22 Jun '11

22 Jun '11

The 'trab' board configuration is broken, and there is nobody who is interested and willing to fix it. Drop it. This includes support for VFD displays which have always been used by this board only.

Then test the address - * lines. Finally, test the cells in the memory now that the test - * program knows that the address and data lines work properly. - * This sequence also helps isolate and identify what is faulty. - * - * o For the address line test, it is a good idea to use the base - * address of the lowest memory location, which causes a '1' bit to - * walk through a field of zeros on the address lines and the highest - * memory location, which causes a '0' bit to walk through a field of - * '1's on the address line. - * - * o Floating buses can fool memory tests if the test routine writes - * a value and then reads it back immediately. The problem is, the - * write will charge the residual capacitance on the data bus so the - * bus retains its state briefely. When the test program reads the - * value back immediately, the capacitance of the bus can allow it - * to read back what was written, even though the memory circuitry - * is broken. To avoid this, the test program should write a test - * pattern to the target location, write a different pattern elsewhere - * to charge the residual capacitance in a differnt manner, then read - * the target location back. - * - * o Always read the target location EXACTLY ONCE and save it in a local - * variable. The problem with reading the target location more than - * once is that the second and subsequent reads may work properly, - * resulting in a failed test that tells the poor technician that - * "Memory error at 00000000, wrote aaaaaaaa, read aaaaaaaa" which - * doesn't help him one bit and causes puzzled phone calls. Been there, - * done that. - * - * Data line test: - * --------------- - * This tests data lines for shorts and opens by forcing adjacent data - * to opposite states. Because the data lines could be routed in an - * arbitrary manner the must ensure test patterns ensure that every case - * is tested. By using the following series of binary patterns every - * combination of adjacent bits is test regardless of routing. - * - * ...101010101010101010101010 - * ...110011001100110011001100 - * ...111100001111000011110000 - * ...111111110000000011111111 - * - * Carrying this out, gives us six hex patterns as follows: - * - * 0xaaaaaaaaaaaaaaaa - * 0xcccccccccccccccc - * 0xf0f0f0f0f0f0f0f0 - * 0xff00ff00ff00ff00 - * 0xffff0000ffff0000 - * 0xffffffff00000000 - * - * To test for short and opens to other signals on our boards, we - * simply test with the 1's complemnt of the paterns as well, resulting - * in twelve patterns total. - * - * After writing a test pattern. a special pattern 0x0123456789ABCDEF is - * written to a different address in case the data lines are floating. - * Thus, if a byte lane fails, you will see part of the special - * pattern in that byte lane when the test runs. For example, if the - * xx__xxxxxxxxxxxx byte line fails, you will see aa23aaaaaaaaaaaa - * (for the 'a' test pattern). - * - * Address line test: - * ------------------ - * This function performs a test to verify that all the address lines - * hooked up to the RAM work properly. If there is an address line - * fault, it usually shows up as two different locations in the address - * map (related by the faulty address line) mapping to one physical - * memory storage location. The artifact that shows up is writing to - * the first location "changes" the second location. - * - * To test all address lines, we start with the given base address and - * xor the address with a '1' bit to flip one address line. For each - * test, we shift the '1' bit left to test the next address line. - * - * In the actual code, we start with address sizeof(ulong) since our - * test pattern we use is a ulong and thus, if we tried to test lower - * order address bits, it wouldn't work because our pattern would - * overwrite itself. - * - * Example for a 4 bit address space with the base at 0000: - * 0000 <- base - * 0001 <- test 1 - * 0010 <- test 2 - * 0100 <- test 3 - * 1000 <- test 4 - * Example for a 4 bit address space with the base at 0010: - * 0010 <- base - * 0011 <- test 1 - * 0000 <- (below the base address, skipped) - * 0110 <- test 2 - * 1010 <- test 3 - * - * The test locations are successively tested to make sure that they are - * not "mirrored" onto the base address due to a faulty address line. - * Note that the base and each test location are related by one address - * line flipped. Note that the base address need not be all zeros. - * - * Memory tests 1-4: - * ----------------- - * These tests verify RAM using sequential writes and reads - * to/from RAM. There are several test cases that use different patterns to - * verify RAM. Each test case fills a region of RAM with one pattern and - * then reads the region back and compares its contents with the pattern. - * The following patterns are used: - * - * 1a) zero pattern (0x00000000) - * 1b) negative pattern (0xffffffff) - * 1c) checkerboard pattern (0x55555555) - * 1d) checkerboard pattern (0xaaaaaaaa) - * 2) bit-flip pattern ((1 << (offset % 32)) - * 3) address pattern (offset) - * 4) address pattern (~offset) - * - * Being run in normal mode, the test verifies only small 4Kb - * regions of RAM around each 1Mb boundary. For example, for 64Mb - * RAM the following areas are verified: 0x00000000-0x00000800, - * 0x000ff800-0x00100800, 0x001ff800-0x00200800, ..., 0x03fff800- - * 0x04000000.

[U-Boot] PCIe Configuration on MPC8544 processor
by António Silva 22 Jun '11

22 Jun '11

Hi all, I am trying to activate a PCIe link between two MPC8544 processor's on a custom board. One processor is configured as Root Complex (cfg_host_agt[0:2] = '111') and the other processor as endpoint (cfg_host_agt[0:2] = '101'). Only PCIe1 is active in both processors (cfg_IO_ports[0:2] = '010') In u-boot I set the following flags in both processors: #define CONFIG_PCI /* Enable PCI/PCIE */ #define CONFIG_PCIE1 /* PCIE controler 1 (slot 1) */ //MJ #define CONFIG_FSL_PCI_INIT /* Use common FSL init code */ In the first processor (configured as RC) I get the following output: * pci_init_board: devdisr=7000008, io_sel=2, host_agent=7 PCIE1 connected to Slot2 as Root Complex (base address e000a000) ....PCIE link error. Skipping scan.LTSSM=0x00 PCIE1 on bus 00 - 00* In the second processor (configured as EP) I get the following output: * pci_init_board: devdisr=7000008, io_sel=2, host_agent=5 ** PCIE1 connected to Slot2 as End Point (base address e000a000) Scanning PCI bus 00 PCI Scan: Found Bus 0, Device 1, Function 0 00 01 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 2, Function 0 00 02 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 3, Function 0 00 03 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 4, Function 0 00 04 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 5, Function 0 00 05 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 6, Function 0 00 06 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 7, Function 0 00 07 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 8, Function 0 00 08 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 9, Function 0 00 09 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 10, Function 0 00 0a 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 11, Function 0 00 0b 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 12, Function 0 00 0c 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 13, Function 0 00 0d 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 14, Function 0 00 0e 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 15, Function 0 00 0f 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 16, Function 0 00 10 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 17, Function 0 00 11 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 18, Function 0 00 12 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 19, Function 0 00 13 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 20, Function 0 00 14 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 21, Function 0 00 15 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 22, Function 0 00 16 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 23, Function 0 00 17 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 24, Function 0 00 18 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 25, Function 0 00 19 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 26, Function 0 00 1a 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 27, Function 0 00 1b 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 28, Function 0 00 1c 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 29, Function 0 00 1d 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 30, Function 0 00 1e 1957 0033 0b20 00 PCI Scan: Found Bus 0, Device 31, Function 0 00 1f 1957 0033 0b20 00 PCIE1 on bus 00 - 00* Each processor is detecting it's own PCIe interface but it is not detecting the other interface on the bus. >From the output of the RC processor: ....PCIE link error. Skipping scan.LTSSM=0x00 from table Table 18-109, the controller doesn't detect any activity on the bus. I proceed trying to check in the HW for any activity in the PCIe bus. I don't see any activity in the bus from any of the processors. Both controller are getting the clock, and apart the PCIe detection both processor are working an proceed the booting stage. Is there any configuration missing in u-boot for the PCIe configuration? Does anyone has any clue/hint to aid in the debugging process of the PCIe interface either for the SW and HW side? Thanks in advance, Antonio

[U-Boot] usbtty for TI davinci DM365 - stdout working, no stdin
by Alex Nancekievill 22 Jun '11

22 Jun '11

Hi, I have been trying to get a working u-boot console over usb for the DM365. I successfully ported the latest versions of drivers/usb and drivers/serial/usbtty from the usb branch to the slightly older version of u-boot supplied with my board and I have been able to get stdout=usbtty to work properly. However I cannot seem to get stdin to work at all. Much googling suggested others have seen the same problem in the past but didn't turn up any fixes. My setup has my Ubuntu desktop host linked by a standard usb to miniusb cable to the board. When I power up the board it appears to enumerate correctly as a device on my host. If I run two minicom sessions on my host, one using serial and the other using usb, I can type on the serial minicom and see the u-boot console on the usb minicom. However setenv stdin usbtty causes u-boot to stop responding to characters entered via either minicom session. I have used wireshark to trace the usb traffic and I have established that this command echo "Hello" > /dev/ttyACM0 Produces this traffic on the USB bus: No. Time Source Destination Protocol Length Info 141 426.991749 host 2.1 USB 64 URB_INTERRUPT in 142 426.991759 host 2.0 USB 64 URB_CONTROL out 143 426.993716 2.0 host USB 64 URB_CONTROL out 144 426.993750 host 2.2 Ethernet 70 URB_BULK out[Malformed Packet] 145 426.993761 host 2.0 USB 64 URB_CONTROL out 146 426.994714 2.0 host USB 64 URB_CONTROL out 147 426.995713 2.1 host USB 64 URB_INTERRUPT in URB status: No such file or directory (-ENOENT) (-2) 148 426.996713 2.2 host USB 64 URB_BULK out URB status: No such file or directory (-ENOENT) (-2) Obviously if you know the problem and can tell me a fix that would be fantastic, if not I have two specific questions which would help me debug this. 1) Where in the u-boot source is the code which is generating the responses with the error codes above? I can't find any point in the code which is capable of setting urb->status=ERROR. Is it possible that the hardware itself can generate these responses automatically? 2) What is supposed to happen when the host sends the BULK packet containing the "Hello" string? It's possible that the error codes in the USB traffic are a red herring. As far as I can tell, the device should raise an interrupt to tell usbtty to read the fifo and pull out the "Hello" string. Since U-boot runs with interrupts turned off, the function udc_irq() in drivers/musb/musb_udc.c polls the interrupt registers to see if it should do anything. However the call to intrrx = readw(&musbr->intrrx); always returns 0 and the call to intrusb = readb(&musbr->intrusb); always returns "Start of Frame" (never seems to get cleared). Usually reading an interrupt register clears it, but this doesn't seem to happen in this case. I confess to being a bit confused about interrupt polling anyway. It seems to rely on the idea that the hardware will set the interrupt registers even though interrupts are disabled so that they can be polled. However the hardware documentation is a bit light on details about what happens with interrupts masked off since that isn't it's intended mode of operation. I've been working on this for several weeks now and would be really grateful for a pointer from an expert. Many thanks, Alex

[U-Boot] how to understand "uboot is 32bit program even it is in the 64bit mips"
by hacklu 22 Jun '11

22 Jun '11

I have a 64bit cnMips borad.In the mail list archives,it says "uboot is 32bit,even in the 64bit cpu." but how to understand that? I have a guess,is the 64bit cpu support a 32bit-mode,then when does it switch to 64bit-mode to load 64-bit linux? btw,I have an other question,according to <see mips run linux>,linux run in the _xkseg_ segment. so the first two bit virtual address in kernel space must be 11, like 11xx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx (64bit). but when I printf a variable' address in a foo driver,is say 0xa80000041c2ea180. not start of _11_. the memory mapping mode has feazed me for _long_ _long_time. Dear Wolfgang(or someone else who can anwser me),thanks -------------- hacklu 2011-06-22
