Fix for known problems

DUT rpi_pico: Remotely flash

This will bring the PICO into boot mode and.

# Force discover all tentacles
op query --poweron
export TENTACLE=5f2c
# Power off DUT
op power --serials=$TENTACLE --off dut
# Press boot button
op exec-infra --serials=$TENTACLE 'set_relays([(1, True)])'
# Power on DUT
op power --serials=$TENTACLE --on dut
# Release boot button
op exec-infra --serials=$TENTACLE 'set_relays([(1, False)])'

If automount is enabled, the filesystem will appear, if not:

sudo mount /dev/sda1 /tmp/x

If you prefer to use picotool:

sudo dmesg --follow

DUT pyboard: format crashed filesystem

See: https://docs.micropython.org/en/latest/reference/filesystem.html

import vfs, pyb, os

DUT NUCLEO_WB55: Remotely flash bluetooth stack

This will bring the NUCLEO_WB55 into programming mode.

# Force discover all tentacles
op query --poweron
export TENTACLE=2f2c
# Power off DUT
op power --serials=$TENTACLE --off dut
# Press boot button
op exec-infra --serials=$TENTACLE 'set_relays([(1, True)])'
# Power on DUT
op power --serials=$TENTACLE --on dut
# Release boot button
op exec-infra --serials=$TENTACLE 'set_relays([(1, False)])'

Flash bluetooth stack

wget https://micropython.org/resources/micropy_nucleowb55_fuwwsinstaller.dfu
dfu-util -a 0 -D micropy_nucleowb55_fuwwsinstaller.dfu

Read bluetooth stack version

# Before flashing
>>> import stm
>>> stm.rfcore_fw_version(0)
(0, 5, 3, 0, 0)
>>> stm.rfcore_fw_version(1)
(0, 5, 1, 0, 0)

# After flashing
>>> stm.rfcore_fw_version(0)
(1, 1, 0, 0, 0)
>>> stm.rfcore_fw_version(1)
(1, 10, 0, 0, 1)
