SDK • Re: [RP2040] sleep_us waits forever

Hmm, using SDK 2.1.1 on a Pi5, with a debug probe and a pico, neither set of debugging instructions in the "getting-started-with-pico.pdf" work.
We follow the steps for "Manually Create your own Project" test.c etc.
Debug with openocd fails with

Code:

embedded:startup.tcl:1427: Error: args[i] option value ('CX') is not valid

Debug with SWD fails with the same

Code:

embedded:startup.tcl:1427: Error: args[i] option value ('CX') is not valid

That CX is coming from, I think: /home/pi/pico/openocd/tcl/target/rp2040.cfg which has

Code:

 $_TARGETNAME_0 configure -event reset-init { rp2xxx rom_api_call 0 CX }

VSCode with Pico extension is installed on the same Pi - debugging blink.c works fine, and breaks at gpio_init(...)
