unable to access /sd

[supersjimmie]

I'm trying to use rshell with my esp32, loaded with MicroPython_ESP32_psRAM_LoBo. Mounting the SDCard works fine:

rshell -p /dev/ttyS12 -b 115200 -n
Using buffer-size of 32

Then when I return from repl with Ctrl-x, I am able to see /flash, but unable to see /sd:

/home/_me_/MicroPython_ESP32_psRAM_LoBo> ls

/home/_me_/MicroPython_ESP32_psRAM_LoBo> ls /sd
Cannot access '/sd': No such file or directory

So I see the local content, I see /flash, but I cannot see /sd.

I tried to restart rshell, but then it fails to load:

When I try again, it starts but still no /sd:

This is happening because rshell only scans the root directories once. I'll see about adding a command to re-scan

[supersjimmie]

I also figured out that this works: ls /pyboard/sd
