The errors I'm seeing are: RD8 failed for run-time address 0x2d WR8 failed for run-time address 0x2d The only code paths that can generate these error messages are in fdt/sxirsb.c, rsb_read_1 and rsb_write_1, when the call to sxirsb_do_trans returns either EIO or ETIMEDOUT. After adding debug code, it seems that the value of 'stat' returned from macro HREAD4 is not RSB_STAT_TRANS_OVER as expected, so sxirsb_do_trans is returning EIO. The value of 'stat' depends on whether it's a read or write operation, but it's always the same: READ 0x103 WRITE 0x003 Whereas the code expects to see 0x001...
