Dear all, My name is Xu LingXiao, i am a computer engineering student from University of Padua. I am interested in the topic "Port payloads to ARM, AArch64 or RISC-V", especially the RISC-V. The reason i want to attend this project is that i just received a risc-v board VisionFive2 from China(i am a Chinese student who study in Italy now), i want to port coreboot to my board. I plan to add payload to risc-v platform starting from qemu and then the real hardware. Now i have gone through the tourial, and here is serial output results(qemu-x86_64): [NOTE ] coreboot-4.19-701-g65c456227e-dirty Sun Mar 05 17:31:38 UTC 2023 x86_32 bootblock starting (log level: 7)...
