I used the latest file and than the previous version, both failed. Only have the usb power led (red) on the board. Any thoughts of how to recover?
Do you have the Beta or RP2350 version? It may be stuck in mass storage mode….have you attempted using the buttons?
Thank you for the follow up. It is RP2350. The issue was with my linux skills around serial access and privacy settings on the browser. Once I set up the linux box serial port correctly everything worked. These are the commands to setup my linux box (ubuntu 22.04):
add myself to serial group:
sudo usermod -aG dialout $USER
add udev rules for SparkFun (1b4f) and RP bootloader (2e8a):
sudo tee /etc/udev/rules.d/99-xrp.rules >/dev/null <<‘EOF’
SUBSYSTEM==“tty”, ATTRS{idVendor}==“1b4f”, MODE:=“0666”, GROUP=“dialout”
SUBSYSTEM==“usb”, ATTR{idVendor}==“1b4f”, MODE:=“0666”, GROUP=“plugdev”SUBSYSTEM==“tty”, ATTRS{idVendor}==“2e8a”, MODE:=“0666”, GROUP=“dialout”
SUBSYSTEM==“usb”, ATTR{idVendor}==“2e8a”, MODE:=“0666”, GROUP=“plugdev”
EOF
sudo udevadm control --reload-rules
sudo udevadm trigger
I had to switch the browser from Firefox to Chrome and all is well. Thank you again for your quick response
