[U-Boot-Users] [PATCH] NXP Semiconductors I2C IP block drivers
by Robert Deliën 06 Dec '06

06 Dec '06

Hi, The patch attached adds drivers for the NXP Semiconductors (former Philips Semiconductors) Nexperia I2C IP blocks as found onboard the PNX8550, PNX8535 and PNX8536. The configuration of the SilverBox development platform has been altered to include these new drivers. This patch depends on the PNX8550 on SilverBox support patch I have submitted at 04-12-2006 13:43. With kind regards, Robert.

[U-Boot-Users] Memory Maps
by Matias Sundman (AS/EAB) 06 Dec '06

06 Dec '06

Hello, In the PowerPC architecture and specifically a Freescale 8270 the HRCW word decides if U-boot is going to be booted from regions: HIMEM 0xFE00_0000-0xFFFF_FFFF or LOMEM 0x0000_0000-0x01FF_FFFF. The CIP field decides the exception vectors; physical address 0xFFFn_nnnn or physical address 0x000n_nnnn. Now, in my current board range I have TEXT_BASE as 0xFFF0'0000 and CFG_FLASH_BASE as 0XFE00'0000. ( 32M ) I my world that makes sense since the flash is mapped in the same range as the bootloader. The start.S file says that things will be fine as longs as we configure BR0 with the same boot ROM link address. Isn't TEXT_BASE the boot ROM link address? In one of the TQM boards ( 8260 ) I see that TEXT_BASE is 0x4000'0000 and the FLASH_BASE is 0xFF80'0000. Here the TEXT_BASE is mapped to a totally different address than HIMEM/LOMEM, the exception vectors and the FLASH_BASE - How is that possible? In other words - Could someone explain what the relationship is actually between TEXT_BASE, FLASH_BASE and the BR0 register settings are? Thx // Matias

[U-Boot-Users] Problems with an E1000 driver
by Marc Lawrence 06 Dec '06

06 Dec '06

Dear All This is my first post - so a quick background. In my spare time I am working on the Qnap Turbostation series of NAS devices; which uses an extended version of U-Boot 1.2. (the modified code - only sandpoint8245.c can be obtained from Qnap). Further board specifications and info can be found at http://scratchpad.wikia.com/wiki/Open_Turbostation:TS101 A colleague is looking at porting the existing U-Boot to version 1.6 - and trying to enable network support (the Qnap version is based on sandpoint 8245). There are two board variants - one with an RTL 8139 ethernet driver (which seems to work no problems); and mine which has an Intel 8250 OEM. Currently my version of the boot code fails; and generates program exceptions. Working backwards we have identified that the failure is occurring in e1000.c between lines 2580 and 2625 - within the e1000_sw_init function. In particular I suspect the code problem is with reading the E1000_STATUS register. <<<>>> if (hw->mac_type >= e1000_82543) { uint32_t status = E1000_READ_REG(hw, STATUS); <<<>>> I had a quick look on the tracker list; and google but was not able to find anything specific. (perhaps im just blind ;-) Currently we daisy chain to the new U-Boot version (as JTAG access is somewhat unreliable at the moment). Thus we download the new version to RAM; then copy it to spare flash; and issue the 'go' command from the U-Boot prompt. I know this is not the recommended path - and therefore wonder if this might also be the associated with the problem. A program trace is attached. I would be grateful if someone could provide some pointers about what might be going wrong. I do know (from debug messages) that the code point never reaches the end of the function - i.e. return E1000_SUCCESS; Many thanks, Marc Ps Please note: to aid initial debugging I had issued extra printf statements - showing "Marc:...".

[U-Boot-Users] Breakage of board ports on new features.
by Pantelis Antoniou 05 Dec '06

05 Dec '06

Hi there, So I'm cleaning my new 834x board in the time period of just two days. There's a commit with a bunch of 834x related fixes which totally broke the board port. I understand that the main code is volatile, but it seems there's a blatant disregard of keeping up a minimum of backwards compatibility. If someone changes code that's supporting a bunch of board ports, please put in some default macros to ensure past behaviour is preserved. I.e. in this case the CONFIG_MPC8349 & CFG_FLASH_SIZE could have easily been defined with the defaults values for the non updated board ports to continue working. Please don't make our lives harder than they are. /me steps down the soapbox. Regards Pantelis

[U-Boot-Users] u-boot won't start on its own anymore...
by mitsy 05 Dec '06

05 Dec '06

My u-boot was running fine until I added some commands. What's happening is that it runs just fine if I have BDI attached or run "reset" command from u-boot itself. However, if I physically power cycle without BDI, it won't start anymore on its own. The functions I have added have nothing to do with the boot-up, and the bdi config file has been always the same so I don't believe it's some initialization issue. I assume something went wrong when the code size changed... Has anyone seen this issue? Any suggestion on what should I look for to fix this? Thank you so much for your advice! Mitsy

[U-Boot-Users] Boot Linux kernel from external HDD, connected to PCI interface.
by Leonid 05 Dec '06

05 Dec '06

Hi: I have AMCC PPC440EP card with Silicon Image 680 PCI-IDE chip, external HDD is connected to it as IDE1 - see snapshot from Linux booting log: SiI680: IDE controller at PCI slot 0000:01:06.0 SiI680: chipset revision 2 SiI680: BASE CLOCK == 133 SiI680: 100% native mode on irq 25 ide0: MMIO-DMA , BIOS settings: hda:pio, hdb:pio ide1: MMIO-DMA , BIOS settings: hdc:pio, hdd:pio hdc: Maxtor 6L100P0, ATA DISK drive ide1 at 0xd105cfc0-0xd105cfc7,0xd105cfca on irq 25 hdc: max request size: 64KiB hdc: 195813072 sectors (100256 MB) w/8192KiB Cache, CHS=65535/16/63, UDMA(133) hdc: cache flushes supported hdc: hdc1 hdc2 hdc3 However this HDD is visible only because Linux kernel happened to have drivers for Silicon Image chip. I boot Linux kernel either from the flash or from RAM. The question is does u-boot itself support Silicon Image or, by other words, can I boot kernel from some partition on HDD (behind this PCI-IDE chip) and if yes - how? Thanks, Leonid.
