[U-Boot-Users] u-boot 1.1.1 and USB mass storage devices
by Shannon Holland 03 Aug '05

03 Aug '05

Hello, We are using u-boot on a Samsung S3C2410 based board and have USB mostly working using the arm920t USB driver. I say mostly working as some mass storage devices work fine, but most do not. Typically the behavior we see when they don't work is a "usb reset" reports the correct number of devices, a "usb tree" will return the correct device tree but "usb scan" will typically return a lot of CLI:TIMEOUT errors and seemingly never return. Sometimes it is able to find the storage device, but reading from it (it has a FAT16 filesystem) will return similar errors. I'm curious if these are known problems or likely to be something in the way we have (or have not) set up usb? Might anyone have some recommendations as to where to start looking? Thanks for any help! Shannon

[U-Boot-Users] [PATCH] - fix minor nit in 8260 FCC ethernet loopback test code
by Murray.Jensen＠csiro.au 03 Aug '05

03 Aug '05

In the 8260 FCC ethernet loopback test code, frames are deliberately sent as broadcast packets, and then any incoming frame is treated as having an error if it is a broadcast packet. This patch ignores the BC status bit on received frames. Cheers! Murray...

[U-Boot-Users] [PATCH] fix typo in mkconfig script
by Murray.Jensen＠csiro.au 03 Aug '05

03 Aug '05

This patch fixes a typo in the "mkconfig" script. The operator "==" is used instead of "=", which works with bash's built-in "test" (aka "[") but not with solaris "/bin/sh" i.e. the script is no-longer standard bourne shell compatible. Cheers!

[U-Boot-Users] problems starting u-boot on AT91RM9200
by David Peters 01 Aug '05

01 Aug '05

I've been trying to get u-boot 1.1.3 to start on an AT91RM9200 system, but I can't get it to start properly. Once u-boot is copied to memory and loader tries to start it, I get garbage on the screen and that is it. The problem seems to be in lowlevel_initS. When it tries to transfer a setup value to a register, that's when it fails. I've tried just changing one value and it still fails. What am I missing? I've read the FAQs in the u-boot manual, but I haven't been able to find the right answer. Thank you!

[U-Boot-Users] U-boot environment in Xilinx System ACE?
by Keith J Outwater 29 Jul '05

29 Jul '05

Greetings everyone - I am working on a port of U-Boot to a custom Xilinx Virtex2 Pro FPGA based board which uses the PPC405 inside the FPGA. The plan is to base the port on the existing ml300 port. The nature of the design requires that the Xilinx System ACE compact flash card be the only nonvolatile memory on the board - no plain old FLASH memory or I2C EEPROM. Therefore, I would like to store the U-Boot environment as a file on the compact flash card. I have checked the latest CVS sources and it appears that no one has implemented this yet. Before I take a crack at it, is anyone planning to do this or in the process of doing it? Does anyone have any advice or caveats? Thanks, Keith

[U-Boot-Users] can't light led after flash restrict to preliminary range
by 刘辉 29 Jul '05

29 Jul '05

hello all: I am new for U-boot and try to port uboot base one TQM866M to my board. I meet a problem and I don't know how to sovle it. Here is the situation: I light a led in cup_init.c -> cpu_init_f( ) as flow: [174] led_init(0x7); /* here is my light led function*/ [175] /* now restrict to preliminary range */ [176] memctl->memc_br0 = CFG_BR0_PRELIM; [177] memctl->memc_or0 = CFG_OR0_PRELIM; And I succeed. But when i move the led function down to line 177 or even to 176, the led doesn't work, as flows: [174] /* now restrict to preliminary range */ [175] memctl->memc_br0 = CFG_BR0_PRELIM; [176] led_init(0x7); /* here is my light led function*/ [177] memctl->memc_or0 = CFG_OR0_PRELIM; Here is the short discription of my board: MPC859DSL OSCLK AM29lv320mb * 1, CS0, 4MByte IC42S16800-t *2, CS1, 32Mbyte I didn't change any words of the tqm866.h, because I thing that: 1. althoung I have only one flash chip, while tqm866m has tow and memc_or1 was set in line 168, but it doesn't take into use. 2. the or and br belong to ram don't take into use at this moment, too. i don't have a debuger like IDE2000, so i was so confused. hope you can help me. regards.

[U-Boot-Users] Re: U-Boot NetBSD OMAP1610
by Detlev Zundel 28 Jul '05

Hi Sam, > Hi, > Good day, > was wondering... would U-Boot be able to boot a NetBSD kernel on a > OMAP1610 processor? The documentation only states NetBSD for PPC > platform and requires a stage2 loader. Does this mean I'll need to > write the OMAP stage 2 loader for NetBSD as well? As I am not too familiar neither with your platform nor with the OS you'd like to boot, I pass this request on to the U-Boot mailing list. Hopefully someone has an answer for you.
