Title: 2c72 blank screen
Hi.
Once the 2c72 stopped working. It turns on, but the screen is blanc, backlight only.
I tried to upgrade in DFU mode in arm1 mode. Upgrade is successfull but no changes.
If I do not disconnect the UART adapter, I see some data incoming into console after power On

1. dC4USK
   
2. f33VZXcCCmf->-5jY kL?333 MachXO2->BUSY
   
3. 333 MachXO2->BUSY
   
4. 333 MachXO2->BUSY
   
5. 333 MachXO2->BUSY
   
6. 333 MachXO2->BUSY
   

Copy the Code

there is no upgrade menu in the software.
