Hi all,
This series is a collection of small fixes I made to TCG for
LoongArch32.
There are still many thing broken, especially on CSRs. More
series following. However this is sufficient to boot 32bit
kernel.
Is there any product introduction about LoongArch32 board? such as MMU
type, memory type(DDR or SRAM), interrupt controller type.
Sure, for LoongArch32 the most accessible board at the moment is chiplap FPGA
[1].
There are also some ASIC designs (BaiXing Project) based on chiplab.
Long in short:
- MMU: PG style
- Mmeory: DDR
- Interrupt controller: custom (Loongson-1C like) connected to CPU's
int pin.
Thanks for the information, Would you like to emulate LoongArch32
chiplap FPGA board in qemu side or other LoongArch32 boards?

Bibo Mao
