[OpenOCD-user] Openocd does not appear to reset the target properly.

[Thomas D. D. <to...@wa...>]

I have a web server on a pico_w. It works correctly. One problem.

When I make a change and reprogram with openocd, the pico_w does not 
restart properly. A browser on a local PC will not load the web page 
until I power-cycle the pico_w.

Code: Select all

 > sudo openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg -c 
"adapter speed 5000" -c "program mycode.elf verify reset exit"

But, the target is not properly reset. A local browser will not load the 
page.
If I cycle power, the local browser will always load the page.

As suggested in the RPi forums, I tried:

 > sudo openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg      -c 
"adapter speed 5000" -c "program kiki_picow.elf verify ; reset halt; 
rp2040.core1 arp_reset assert 0 ; rp2040.core0 arp_reset assert 0 ; exit"

No improvement.

What am I doing wrong? Any ideas?
