In board's notation, bank 0 is -the one at the address of 0xFF800000 and bank 1 is the one at the -address of 0xFF000000. On power-up the processor jumps to the address -of 0xFFF00100, the last megabyte of the bank 0 of flash. Thus, -U-Boot is configured to reside in flash starting at the address of -0xFFF00000. The environment space is not embedded in the U-Boot code -and is located in flash separately from U-Boot, at the address of -0xFF008000. - - -U-Boot test results --------------------- - -x.x Operation on all available serial consoles -
