Hello Robert, I was going through this forum to resolve my current problem with custom board copied from Beaglebone Black for our company's specific need. We are using AM3352 TI cpu and Alliance AS4C256M16D3 MEMORY chip set which has tCK 2.5 min 3.3 max.
Hence, I board memory leveling though CCS 6.1.0 for DDR2, The following I noticed 1/ Jtag initialise and connect cortex A4 memory test seems to succeed 2/ When I try to set break point hard at s_init() CCS does NOT get set breakpoint 3/ Using Assembly code stepping system reach to following stage U-Boot SPL am335x (july 27 2015 16:46:16) Incorrect Magic Number (0xffffffff) in EEPROM Could not get Board Id. Unknown board, cannot configure pinmux. ####ERROR ###### Please RESET the board #### AND system hung permanently. After setting message and enumerated my structure am335x_baseboard_id in the function read_eeprom() the program fall out from lack of magic number while reading MLO file AS I noticed there were no values in the am335x_baseboard_id header structure. The question IS this check can be by passed? Including all EEPROM info board name serial SKU etc I ran diff on the provided link for the board.c which exists on git repo am335x/board.c I did not found any difference. If you please shed some light on this problem I am stuck on this almost a week. Much appreciated for your help.
