Hi I am new entry to U-Boot users list. We are using CSB637 board for our project. We plan to use U-Boot as bootloader since it is easy to port for our custom made board in future. Has anybody used u-boot for CSB637. If so what changes i need to do in u-boot code.please help. We tried to download u-boot1.1.2 to CSB637 board but it is not responding after message "Downlaoding U-boot...".
please reply.
regards Mohan

Hi,
the necessary patches were sent to the list on the 3.rd of may (see the list archives) and are still pending in Wolfgang's queue.
BTW, you should fetch U-Boot from CVS; 1.1.2 is quite old.
Cheers Anders
Hi Anders Thanks for u'r suggestion. I downloaded u-boot1.1.3 from net. We are now reducing the PLL clock to < 180Mhz.
Has anybody used u-boot for CSB637.......
To build a u-boot image, what is the NAME_config parameter of 'make' command. will it work if i give the command make AT91RM9200dk_config or is it make cogent_common_config or is there any seperate config file for csb637 board.
Can we use the loader.bin, boot.bin that was supplied with Atmel's development kit(AT91RM9200dk) for CSB637 board.
pl. help regards mohan

I set the clocks at 184.320MHz, since this is the value the Cogent-supplied boot-loader uses, and the value Linux expects. If the CSB637 doesn't work with that clock frequency, it's really Cogent's problem.
or is there any seperate config file for csb637 board.
yes...
make csb637_config
...but please bear in mind that the patches I mentioned have not been merged yet - you have to apply them yourself first.

No (and you don't need them).
