Dear : Thank you . I'm porting U-Boot to the WindRiver MDP8xx PRO board.Now I think I should run the U-Boot on my board in the simpliest way, so I just configed the necessary devices like FLASH ,DRAM . I can provide anything I have ,and thank you very very much .The include/configs/windriver.h and board/windrive/windriver.c have been included in the attachment.The MDP8xx PRO UM is too large to be attatched here.

[U-Boot-Users] RESET on Lite5200
by Pascal FIFRE 25 Oct '03

25 Oct '03

I've used a Lite5200 (Version 2 : 64MB SDRAM, 16 MB FLASH) and I try to use U-Boot on It. I worked for now with a WireTAP JTAG debugger. I've flashed the latest code found in CVS tree and compile it with ppc_8xx. When I Reset (hard or soft reset) the cpu, the U-Boot doesn't work at all (I didn't see anything on the console). But when I use the debugger to reset the CPU and start the code in FLASH, U-boot works fine. The board has the default RESET configuration (Boot High, etc.). In the same way, when I flash the MOTOROLA DBBUG monitor on the board and RESET, it works. Can you help me ? Thanks

[U-Boot-Users] U-Boot and PPC
by Srikanth Sherman 23 Oct '03

23 Oct '03

Hello, I just found this list, so please bear with me if my questions are basic. I'd like to use the 440GX (or 440GP) so I got the ELDK and U-Boot 0.4. The ELDK doesn't specifically say that it supports the 440 series, do you know if anyone has been successfuly in building 440 binaries using ELDK? Also, I've never used U-Boot before, but I'm *assuming* that once I get U-Boot running on my board, I can just load up the application built with ELDK (assuming of course the it can build 440 compatible binaries) and it should work? Am I completely missing something here? Intially, I just want to get a simple "hello world" program working (ie, not attempting to boot Linux yet) Thanks very much for your time! Sri

[U-Boot-Users] Multi-file problem
by Rick Bronson 23 Oct '03

23 Oct '03

Hi, I found a problem with Mutli-file use of mkimage (using "-T multi") and fixed in my old u-boot-0.4.0 but my fix seemed to filter through too many files when I tried to do it (more correctly) on the cvs tree. Here's the problem (using 21-Oct-03 cvs files): When this address in cmd_bootm.c:1122 inside print_image_hdr() (is caculated: ulong *len_ptr = (ulong *)((ulong)hdr + sizeof(image_header_t)); it points to memory that wasn't copied back on cmd_bootm.c:174: memmove (&header, (char *)addr, sizeof(image_header_t)); because len_ptr points to the address header[1] and the memmove only moved header[0]. So I changed line 140 to: image_header_t header[2]; /* enough room for multi-image's size bytes too */ and all occurances of memmove (&header... from: memmove (&header, (char *)addr, sizeof(image_header_t)); to: memmove (&header, (char *)addr, sizeof(header)); But cmd_autoscript.c,common_util.c, armlinux.c uses &header and I'm not sure if this is the right fix. Maybe someone who knows this stuff can give me some direction. Thanks much. Rick

[U-Boot-Users] ICACHE and ARM ???
by Steven Scholz 23 Oct '03

23 Oct '03

Hi there, my new board using Atmel's AT91RM9200 is booting now straight up to the bash! But I noticed that the cache is _not_ enabled while U-Boot is running. That makes tftp und bootm very slow indeed. Now, enabling and disabling icache by accessing CP15, Reg 1 using a BDI2000 works fine. The speed up is remarkable. But the icache command does not work as I woud ecpect: MulitIO> icache p15/c1 is = c000007c Instruction Cache is OFF MulitIO> icache on icache_enable(145) p15/c1 is = c000007c write c000107c to p15/c1 p15/c1 is = 0000617c p15/c1 is = 0000617c Instruction Cache is OFF Hmm. So instead of just setting Bit 12 three other bits are set. Is someone using icache on ARM systems?

RE: [U-Boot-Users] Problem with LAN91C113
by Scott McNutt 21 Oct '03

21 Oct '03

Rick, I had the exact same problem when using LAN91C111 on the Nios DK-1C20 board (same status & incorrect length). You may need to define CONFIG_SMC_USE_32_BIT. If your bus interface to the chip is 32-bits, a full 32-bit read might be occuring when the data register is read. This throws away the second 16-bit word of the packet buffer (which is the packet length) -- so you end up skipping every other set of 2-bytes after reading the incorrect length.

[U-Boot-Users] Successful Port to PrPMC800
by Mark.Lightfoot＠sita.aero 21 Oct '03

21 Oct '03

Hello, I've successfully ported U-Boot to the Motorola PrPMC800. Support for FLASH, PCI, IDE and networking have bee successfully enabled. It has been in use now for several weeks in a stable form. I do have one lingering problem of not being able to turn on the L1 and L2 data caches. Doing so apparently causes the system to hang. Unfortunately I don't have a BDI2000 setup for this board to better debug the problem. I used just a good ol' console and plenty of printf statements to do the port. I can't give a specific time for when I will have the port submitted for a future release of U-Boot. But I will do it. I'd like to fix my cache problem first and I have to finish the rest of the project for which U-Boot is just one part. And that may be awhile. Regards, Mark.

I'm investing the possibility of porting U-Boot to the Motorola PrPMC800 and possibly the Force Computer PowerPMC-260. As anyone already done the port to these boards? See URL: http://mcg.motorola.com/cfm/templates/product.cfm?PageID=925&ProductID=175&… And URL: http://www.forcecomputers.com/products/viewDetail.cfm?productTypeID=2&produ… The goal is to boot Linux from and IDE drive which the boot firmware of these boards do not support. I don't have the Motorola hardware yet ( delivery is six to eight weeks! ) but it is the intended hardware for the project I'm working on. I do have the Force Computer hardware right now. So, I may proceeded to port U-Boot to it first and do my the remainder of the Linux development work with it in the mean time.

[U-Boot-Users] How to optimize bit bang interface?
by Steven Scholz 21 Oct '03

21 Oct '03

Hi there, I am trying to configure an Altera FPGA using the so called "passive serial interface". Basicly it follows the scheme "clk low, data out, clock high". For testing I wrote the loop ts = get_timer (0); while (1) { if (get_timer (ts) > 10 * CFG_HZ) break; /* Deassert the clock */ (*fn->clk) (FALSE, TRUE, cookie); /* Assert the clock */ (*fn->clk) (TRUE, TRUE, cookie); }; fn->clk() is the function that the common FPGA code uses: int inline fpga_clk_fn(int assert_clk, int flush, int cookie) { if (assert_clk) *AT91C_PIOB_SODR = FPGA_DCLK; else *AT91C_PIOB_CODR = FPGA_DCLK; return assert_clk; } I noticed that this is awfully slow. I get arounf 50kHz using an AT91RM9200 running at 51MHz (core @ 171MHz). Could someone give me a hint how to optimize stuff like this for speed? Thanks a million, -- Steven Scholz imc Measurement & Control imc Meßsysteme GmbH Voltastr. 5 Voltastr. 5 13355 Berlin 13355 Berlin Germany Deutschland fon: +49 30 467090-0 Tel: 030 / 467090-0 fax: +49 30 4631576 fax: 030 / 4631576

[U-Boot-Users] Problem with LAN91C113
by Rick.Lee 21 Oct '03

21 Oct '03

The Ethernet Chip on my board is SMSC LAN91C113,the driver I used is smc91111.c. I've defined CONFIG_DRIVER_SMC91111,undefined xxx_USE_32_BIT undefined xxxx_EXT_PHY. When u-boot runs up, I try to ping my host from u-boot,but the sniffer on my host cannot catch any hardware packet,but my host sends ARP REPLY packet to my board. and the sended packet is captured by sniffer.Unfortunitly,board does'nt seem to have received right packet.I've enabled ET_DEBUG,It prints: RCV: STATUS 42 LENGTH 8. AND LEDA & LEDB both lights! What is the reason? Can you give me some ideas? Thanks a lot! Ricky
