Saw a blog: https://www.luffca.com/2022/10/linux-tang-primer
In order to make it to work, how to modify the cmd: python -m litex_boards.targets.sipeed_tang_primer --build --load
e.g. --cpu-type=vexriscv_smp
how to conf,let to see sdram in the soc (8M SDram), modiy rom size(64k ROM)

[hai4john]

need to modiy litex_boards/platforms/sipeed_tang_primer.py and add "ddram" and "sdcard" ?

@hai4john: You can add --help to your build-command.

• DRAM should be enabled by default.
• Adding 2 CPUs with VexRiscv-SMP: --cpu-type=vexriscv_smp --cpu-count=2
• Adding SDCard: --with-sdcard
• Etc...
