Re: [U-Boot-Users] Flash Replacement for AT91RM9200-EK

Generally, the processor will use the slowest access time to fetch the boot code when it come out of the reset state. So, are you sure the default MCLK is 60MHz/4? You look up the datasheet about What is the defaut MCLK's freq? of cause, you can measure it directly.

Hello Dave, i am not shure, what the exact clocking rate is. All i know is, that there is a "slow clock" at 32768Hz and a "fast clock" at 18.432MHz connected. The first Opcode fetches after Reset seem to be clocked with the "slow clock" and now the Initialization by U-Boot sets up the timing of the EBI - but what timing is selected for the parallel Flash ?
