On other CPUs in this forum I have seen people read device registers from TI uboot using “md” command. but I cannot, all I get all zeros.
for instance md 0x4a003c3c returns 00000000. But in Linux devmem2 0x4a003c3c returns the proper data. Is this a limitation of this uboot or what? I want to read and set some registers in uboot before boot.
