Re: HSS Issue with GCC 10, Qemu Setup for microchip-icicle-kit

[Rahul Pathak]

I followed the same link. I will elaborate what is happening at my end -

First -

Used the same versions as per the doc. Built HSS 2020.12 and used core-image-minimal-dev-icicle-kit-es-sd-20201009141623.rootfs.wic.

Upon executing the qemu launch command as per the doc, it's just waits for the connection on another serial console -

info: QEMU waiting for connection on: disconnected:unix:serial1.sock,server=on

Even if I open sudo minicom -D unix\#serial1.sock, which remains offline always.

Second -

If I remove the "-chardev socket,id=serial1,path=serial1.sock,server=on,wait=on -serial chardev:serial1" from the

qemu launch command then HSS boots but stops after sbi_init on all the cores and put the cores in Idle -

[5.443011] boot_download_chunks_onExit(): boot_service(u54_1)::u54_1:sbi_init 80200000

[5.444960] boot_wait_onEntry(): boot_service(u54_1)::Checking for IPI ACKs: - -

[5.447962] boot_wait_handler(): boot_service(u54_1)::Checking for IPI ACKs: ACK/IDLE ACK

[5.449343] RunStateMachine(): boot_service(u54_1)::Wait -> boot_service(u54_1)::Idle

Third -

If I take the latest release of HSS 2021.04 and build with gcc10, it does not boot at all even if I remove the serial1 like in the second case.

Thanks

Rahul

The HSS issue of GCC 10.1 was already fixed in the HSS mainline.

Could you please elaborate which part does not work? Is that Linux,
HSS, or U-Boot?

I have not tried Yocto Linux yet with Microchip Icicle Kit on QEMU. I
only tested the Linux images released by Microchip.
Could you please follow the instructions @
https://qemu.readthedocs.io/en/latest/system/riscv/microchip-icicle-kit.html
to see which step might be wrong on your side?
