The main problem is that this board uses the default Hard Reset -Configuration Word and not the 4 bytes located at start of FLASH because at -0xFE000000 is no FLASH. The FLASH consists out of 4 chips each 16bits wide. Be -carefull, the bytes are swapped. So DQ0-7 is the high byte, DQ8-15 ist the low -byte. - -The icache can only manually be enabled after reset. -The FLASH and main SDRAM is working with icache enabled. -The local SDRAM can only be used as data memory when icache is enabled. -If U-Boot runs in local SDRAM, TFTP does not work. -The functions in mii_phy.c are all working. Call mii_phy_discover() out of -eth_init() and solve the linker error. -I2C, RTC/NVRAM and PCMCIA are not working yet. - -TODO -The 32MB local SDRAM is working but not shown in the startup messages of -U-Boot. If you locate U-Boot or any other program to this area it won't run. -Turning the ichache off does not solve this problem. - -As I won't buy another RPX Super there might be some little work to do for you -getting this U-Boot port running on the final board. - - -frank.morauf@salzbrenner.com |
