[U-Boot-Users] Any *urgent* bug fixes pending?
by Wolfgang Denk 20 Oct '03

20 Oct '03

Hi everybody, getting closer to a 1.0.0 release I would like to verify that there are no _urgent_ bug fixes left. Can you please verify that I checked in all _urgent_ patches / bug fixes sent to me, or that I acknowledged that I will postpone the modifications until after 1.0.0?

by Steven Scholz 20 Oct '03

Hi there, I think there's terrible bug in the U-Boot ethernet driver for AT91RM9200 cpus. The function at91rm9200_EmacWritePhy() does not write the correct data. Attached patch fixes that.

[U-Boot-Users] cpu/arm925 timer fixes.
by Woodruff, Richard 20 Oct '03

20 Oct '03

Hello, This patch fixes a few bugs which made udelay() not work properly on 925 based systems. A while back when I increased my boards clock speed I ran into quite a few problems which resulted in these fixes. I think the Innovator should be switched over to use a real udelay code instead of its busy spins. They do not scale at all with clock speed, and do not keep the useful timestamp properly updating. Regards, Richard W.

I know that you are aware of the "silent" stuff. Why do we need something new like "quiet" now? I don't like to have 20 different implementations of more or less the same feature. Also, please consider the use of "setenv stdout nulldev".

[U-Boot-Users] Stack Size for MPC8xx???
by Steven Scholz 18 Oct '03

18 Oct '03

Hi there, does someone know how big the stack is for an MPC8xx based boards? I had this problem: I started porting U-Boot to my new AT91RM9200 based board. After doing the flash code I tried "saveenv". Simple reading, writing and erasing was working. But the board crashed when doing "saveenv". I found these lines in common/env_flash.c: int saveenv(void) { ... #if defined(CFG_ENV_SECT_SIZE) && (CFG_ENV_SECT_SIZE > CFG_ENV_SIZE) ulong flash_offset; uchar env_buffer[CFG_ENV_SECT_SIZE]; #else ... /* copy old contents to temporary buffer */ memcpy (env_buffer, (void *)flash_sect_addr, CFG_ENV_SECT_SIZE); I have CFG_ENV_SECT_SIZE = 64K and CFG_ENV_SIZE=4K and realized that my stack was far to small to save an 64KB flash sector. The funny thing is that I never worried about that issue. And it never seems to be a problem on our MPC8xx based boards...

[U-Boot-Users] problems about flash setting
by wang cheng 18 Oct '03

18 Oct '03

dear all! sorry ,but i really don't understand. 1.What's the meaning of flash memory banks,is the number of flash chips? ie:if i have 2 chips of 29f040s on my board,then the CFG_MAX_FLASH_BANKS should be 2,right? 2.What's the meaning of FLASH_BASE0_PRELIM and FLASH_BASE1_PRELIM, Is the FLASH_BASE0_PRELIM should be set to the flash_base_addr that defined by cs0? Then what about flash_base1_prelim? 3.What's the difference between br/or_prelim and br/or_remap and their respective function ??Is the br/or_remap must be set or optional depended on my board? Thanks very much for any help!
