LM058: Firmware update failure
“I accidentally removed the power for the LM058 adapter during a firmware update. Now when I power it on all three LED’s light up. I cannot connect via serial and the adapter is not seen via USB either”
Unfortunately this means that the adapter is broken. You won’t be able to communicate with it with UART, or upgrade the firmware over USB. The only possible way to reprogram the adapter is through the debug-SPI pins (you would need to remove the casing and solder wires on the USB programming connector), but we cannot support this for customers.
