My argon is blinking the SOS 10-blink pattern. It fails to respond to the mode button but does respond to the reset button. Grounding the MD pin has no impact.
I used the OPENOCD command with both argon 3.0.1 and also 2.0.1 with commands like this:
bin/openocd -f share/openocd/scripts/interface/cmsis-dap.cfg -f share/openocd/scripts/target/nrf52-particle.cfg -c “adapter_khz 1000” -c “transport select swd” -c “init” -c “reset halt” -c “nrf5 mass_erase” -c “flash write_image c:/temp/argon_2_0_1.hex” -c “reset” -c “exit”
During the openocd commad, the SOS pattern stops with the LED off. Once the command finishes, the SOS pattern resumes. Here’s an example output:
image c:/temp/argon_2_0_1.hex" -c “reset” -c “exit”
