In Part 1 we brought up the bootblock and romstage, mapped all USB, SATA, and PCIe ports. In Part 2 we added the USB and PCIe devicetree descriptors and integrated Phoenix openSIL as a submodule, reaching CCX initialization successfully - but the platform stalled during PCIe initialization because the Phoenix PoC openSIL was written for mobile CPUs, not the desktop AM5 variant used on the B850-P. https://beta.blog.3mdeb.com/2026/2026-03-06-msi_pro_b850p_part2/ Fri, 06 Mar 2026 00:00:00 +0000 https://beta.blog.3mdeb.com/2026/2026-03-06-msi_pro_b850p_part2/ Introduction This blog post continues where Part 1 left off. As a quick recap: we successfully brought up bootblock and romstage on the MSI PRO B850-P using coreboot, but ramstage halted waiting for CPU core initialization that depends on OpenSIL. We also mapped all USB, SATA, and PCIe ports during the hardware-topology discovery phase. Before diving into the new content, there is one important development to mention: all Dasharo code has been rebased from coreboot 24.
