Hmm.. mabe something with at91_clock_init() This is called in arch_cpu_init(), and at the end, clocks are stored in arch/arm/cpu/arm926ejs/at91/clock.c in "static unsigned long" vars ... as this code runs before relocation, this seems to me as it could be the reason for your problems ... but I can;t try it here ... can you check this? > mci: setting clock 0 Hz, block size 512 > mci: setting clock 0 Hz, block size 512 > mci: setting clock 0 Hz, block size 512 > mci: setting clock 0 Hz, block size 512 > Device: mci > Manufacturer ID: 89 > OEM: 303 > Name: NCard > Tran Speed: 25000000 > Rd Block Len: 512 > SD version 2.0 > High Capacity: No > Capacity: 2006974464 > Bus Width: 4-bit > > Do I understand right what the required changes are: > > 1. change dram_init Yep. > 2. make sure TEXT_BASE is correct as to where u-boot is loaded > by a preloader and is NOT pointing near top of RAM.
