Hello,
I try to update the new u-boot.bin (128k) with an u-boot already run in a ppc405ep board (8mb flash, 32mb ram),
using serial port, Using original u-boot to install another u-boot.bin, for example: flash memory from ff800000 to ffffffff, u-boot.bin in fffe0000 to ffffffff,
. loadb 0x1000000 . kermit send u-boot.bin Then we can see u-boot.bin (128k) shows in 0x1000000 - 0x1020000,
if copy from memory to flash, After protect off 0xfffe0000 sector And erase 0xfffe0000 sector Cp.b 0x1000000 0xfffe0000 0x20000 but no u-boot.bin shows in 0xfffe0000 - 0xfffffff, all byts from fff80000 to ffffffff become 008000880 .
if copy from memory to memory cp.b 0x1000000 0x1050000 0x20000 In 0x1050000 - 0x106ffff u-boot.bin shows right.
So cp.b copy from memory to memory workes , but cp.b copy from memory to flash does not work!
the cp.b seems just could copy memory to memory, but how to enable it copy from memory to flash?
Thanks a lot!
Best regards
Tyler
