I hope someone may be able to help with the problem I have at the moment.I have just received my custom LPC3250 board which is based on the EA3250 evaluation board. I can sucessfully download the kickstart and s1l bootloaders and get the serial prompt on reset.
Using the s1l monitor program I have verified the SDRAM is working and I can read & write flash. However the next time I press reset or power cycle the board the bootloaders do not start. The only way to recover is to re-download the s1l bootloader and it will boot up fine after the first reset but again fails on any subsequent resets. I don't have JTAG at the moment so can't use that to debug the bootloaders.
One other question. In the debug monitor when I try the NAND Flash "read" command I always get an error when I try to read the first 10 sectors anything after that is fine. This also happens on my EA3250 board so doesn't seem specific to the new hardware. Is this normal?
Thanks Ian
