Hi, I am trying to use u-boot-1.1.4 with AT91RM9200 based board. Using Parallel flash all works perfectly, but if I try using u-boot stored in Dataflash i face to some problems and comparing two cases I see that CPU clock are different. Seems that is required a RomBoot provided by Atmel which launch u-boot. Is it really necessary ? Maybe I've miss an option that avoid RomBoot usage ? CONFIG_SKIP_LOWLEVEL_INIT seems used only with parallel flash, what when using Dataflash ?
Boot from Dataflash : define CONFIG_SKIP_LOWLEVEL_INIT 1 Machine: Atmel AT91RM9200 Memory policy: ECC disabled, Data cache writeback Clocks: CPU 59 MHz, master 59 MHz, main 18.432 MHz ^^^^^^^^^^ Boot from Parallel flash : undef CONFIG_SKIP_LOWLEVEL_INIT Machine: Atmel AT91RM9200 Memory policy: ECC disabled, Data cache writeback Clocks: CPU 179 MHz, master 59 MHz, main 18.432 MHz ^^^^^^^^^^
Every hint will be appreciated TIA
