Raspberry Pi CM4 and OpenOCD

by Anne Macedo

I’m trying to debug the Renesas XHCI bug using the Raspberry Pi CM4 (which has a PCI interface). However, it doesn’t support IOMMU, so I can’t debug using QEMU… I bought a JTAG then and I’m going to use it with OpenOCD :)

Installing GDB Multiarch on Arch Linux

yay -S gdb-multiarch

I’ve built openocd from the source.
