"devmem2-like" utility in HSS' TinyCLI?

[haroldnelson-2021]

Is it feasible to add a "devmem2-like" utility to the HSS' TinyCLI so users can manually read-write their PF SOC fabric resources, assuming the PF SOC board has a UART connected to the PF SOC? SmartDebug, of course, provides read-write access but this uses the JTAG interface and does not exercise the functional logic path.

Hi @haroldnelson-2021 , there is debug menu in HSS. If you type "debug" you can look at the submenu. The hexdump utility should do what you are looking for.

I see "hexdump" in my TinyCLI. Is there any help for the arguments and usage? Thanks.

Supported subcommands:
BEU HEALTHMON SM IPI CRC32 HEXDUMP OPENSBI SEG L2CACHE PERFCTR WDOG

hi @haroldnelson-2021 , if you type debug hexdump with no args it should show usage info. You have to write the start address followed by length in hexadecimal format "0x
