CH592F: isp flash/upload failed

[KenjutsuGH]

When I try to upload to my WeAct CH592F board using the isp protocol, I get the error:

Configuring upload protocol...
AVAILABLE: isp, minichlink, wch-link, wlink
CURRENT: upload_protocol = isp
Uploading .pio/build/genericCH592F/firmware.elf
Error: Device type of 0x22 not found
*** [upload] Error 1

When I go to the project directory and manually invoke wchisp (0.2.3), it works:

pio upgrade
You're up-to-date!
PlatformIO 6.1.15 is currently the newest version available.

My platformio.ini:

[env:genericCH592F]
platform = ch32v
board = genericCH592F
framework = noneos-sdk
upload_protocol = isp

I am using macOS Sonoma 14.5 (23F79) M1

When I go to the project directory and manually invoke wchisp (0.2.3), it works:

Can you copy your latest wchisp version into ~/.platformio/packages/tool-wchisp/ to overwrite the old version? Does PlatformIO upload then?

[KenjutsuGH]

Thank you @maxgerhardt, that solves the problem

[maxgerhardt]

Thanks for letting me to, I'll try to update the packages in a scripted way some time in the future.

Just ran into the same, installed the 2.3 from cargo and copied it, now it works

The updated tool-wchisp pacakges have been pio pkg publish'ed today, but are in manual review by the PlatformIO team before they're visible.
