Ignoring the SHA mismatch and proceeding with installation will install arm-none-eabi-toolchain, but the subsequent morello-scp-firmware build fails.

[jrtc27]

Ok, so the toolchain one looks to be that we don't provide an expected hash and something there has regressed, which needs fixing (but we probably should provide the expected hash too).

As for the build failure, no clue, and if you don't provide the error then I have no hope of helping you.

But why are you building the firmware yourself anyway? Morello boards have pre-built firmware available from Arm, and we distribute pre-built firmware for the FVP if you really want to endure using that rather than CHERI QEMU.

[vzaliva]

I did not include error messages for morello-scp-firmware because I suspect arm-none-eabi-toolchain built with the wrong hash, was likely the root cause. As to prebuilt firmware for FVP, are these installed via the morello-firmware target? If so, they are missing, for example, scp_fw.bin mentioned here and here.

I think scp_ap_image.bin is what you're looking for (perhaps it got renamed, or varies between FVP and board?); I see cheribuild pass -C soc.scp_qspi_loader.fname=$HOME/cheri/output/morello-sdk/firmware/morello-fvp/scp_ap_image.bin -C soc.mcp_qspi_loader.fname=$HOME/cheri/output/morello-sdk/firmware/morello-fvp/mcp_image.bin to the FVP.
