Hi everyone,
When running U-Boot in M-Mode on the QEMU sifive_u machine, I get a Load Access Fault when trying to access one of the SPI controllers (QSPI 2) using md.w 0x10050000 1
.
Any reason why this is happening?? I’ve got the same problem with the UART controllers. Note that in this setup there is no SBI, as uboot is start with Qemu’s -bios option. Could u-boot be enabling memory protection for MMIO devices??
Thanks.
