Suddenly, my Smoothie won't boot

Hi All,

I turned the K40 today and the LED 4 doesn’t light up (nor the rest), 3.3V is fine. The suggestion is that its the SD card, so I took it out, lost it (!), went and bought another, and put the config and firmware.bin a fresh FAT32 partition. Still no joy. Blew the SD socket out with compressed air, no different. Any ideas appreciated.

Cheers

Hello,

When you tried to upgrade the firmware, did the led toggled? You can check on your SD card that the firmware file has been renamed to FIRMWARE.CUR.
