All i know is, that there is a "slow clock" at 32768Hz and a "fast clock" at 18.432MHz connected. The first Opcode fetches after Reset seem to be clocked with the "slow clock" and now the Initialization by U-Boot sets up the timing of the EBI - but what timing is selected for the parallel Flash ?

If you can call arm-linux-gcc from the command line, then there is no reason that the U-Boot Makefile would not be able to do the same. > I think the problem is about ubuntu configuration itself. No, you must be doing something wrong. But without better information (like showing us the precise commands you used, and the error messages you got) it is impossible to provide better help.

[U-Boot-Users] How to include ML403 supported by U-boot
by Ming Liu 18 Aug '06

18 Aug '06

Dear wolfgang, Now I am trying to use u-boot to boot my Linux kernel image(2.6.16) using tftp and then mount the file system using NFS in ML403 board. But I noticed that in U-Boot 1.1.4, there is no ML403 supported.(There is only ML300 supported.) So can you tell me how to make ML403 supported by U-Boot? Shall I write the specific board configure by myself, or there is some patch for it? I have asked this question before but nobody give me an exact answer. So I think it's better to ask the author directly. Thanks for your help.

Hi u-boot I have tried to compile u-boot for OMAP5912 usins ubuntu drapper as a host machine. I got error linux-arm-gcc not found, I 'm sure gcc is in the path, I can call it in shell. I 'm very new.

To change the Wait States there must a Program be already running. The first Opcode Fetches after Reset can't be slowed down by any programmable Logic. This Timing is adjusted by Hardware, but what are the Parameters for the AT91RM9200 ? > > -Dave > > >

[U-Boot-Users] pcf8563 RTC access; undefined CFG_I2C_RTC_ADDR
by Ken.Fuchs＠bench.com 18 Aug '06

18 Aug '06

I configured pcf8563 RTC, I2C, date, and the I2C command for a PPC board. When I compiled U-Boot, CFG_I2C_RTC_ADDR used by pcf8563.c was undefined. What is the recommended way of determining the correct value of CFG_I2C_RTC_ADDR for pcf8563.c and a PPC board? I simply want to be able to set and read my RTC using U-Boot. (I searched for an answer via google and I also searched the u-boot-users mailing list archive, but I was unable to find a answer. Sorry.) Sincerely, Ken Fuchs

[U-Boot-Users] Flash Replacement for AT91RM9200-EK
by Erdmann, Thomas 18 Aug '06

18 Aug '06

Hello List, i use a custom Board based on the AT91RM9200-EK. Now i want to Replace the Nor Flash AT49BV6416 by a larger one from Spanion. The older Atmel chip specifies 70ns Access Time, the most usual Spanion chips are slower in the 100ns Range. As i read the CPU Datasheet correct at 60MHz EBI Speed the slowest Factor 1/4 gives 67ns Cycle Time. Does anyone know, how Access Time for the parallel Flash is calculated and what Speed Grade is needed for a stable U-Boot out of it ? Could a slower (100ns) Chip be used, how can this be adjusted ? Are there any additional Parameters for the Flash Chip to care of (Burst Mode, Multi Bank) ? Thanks Thomas
