Hi,
I bought a pico a while back and used it for a bit and then decided to to run micropython on it as a comparison. I didn't really use it that much with micropython so decided to swap it back to running espruino. Initially i tried to just re-flash it using the web IDE but it would not connect to the board (It did detect it though). I then tried to re-flash it using dfu-util (i'm running linux and used a pencil to short boot0/btn) as i had done to put micropython on it in the first place and this seemed to work (got no errors). I then got rid of the graphite but since then it has refused to power up and now nothing happens - no lights at all. The web IDE indicates no usb port (/dev/ttyACM0) only internal serial and both lsusb and dmesg show nothing. Could this be caused by not clearing out the graphite properly (i thought i had) or have i bricked it?Any help is much appreciated.
Cheers.
HI Gordon,
Thanks for the reply.
Yeah you were right , i was using one of the Travis ones, when i re-did it with the correct file and eventually got it into DFU mode it uploaded fine and i now have the PICO running again - thanks for that.
One quick question: you have a kindle version of the making-things-smart for on-line purchase, is there also a straight PDF version for on-line purchase?
Cheers.
