I recently constructed a Menta board, which worked (for a while). For some reason, recently, the FTDI friend seems to not like to talk to the Menta board, even though I know the bootloader is functioning (the LED is doing its blinky thing). I did have a custom shield connected while I was programming the MCU, so I was wondering if anybody else have observed the Menta appearing to be (mostly) bricked because of a bunch of LED's drawing power from the shield connectors while the FTDI friend is trying to talk. Maybe it is the FTDI friend that is bricked. The avrdude error code is the infamous 500 code (not in sync). Is there a maximum current draw while downloading the sketch which does something (wonderful/unexpected) with the fuses etc? Is the situation recoverable or do I start from scratch?
