I had one Colibri T30 board purchased back in 2016 and never used. I decided to set up a WEC2013 image on it and used nvFlash tool for that purpose.
During attempt to load up the image I got this ERROR message about missing serial number of board (taken from log):
Nvflash version 2.6 started rcm version 0X30001 System Information: chip name: unknown chip id: 0x30 major: 1 minor: 3 chip sku: 0xb1 chip uid: 0x0000000000000000015d4b337534240f macrovision: disabled hdcp: enabled jtag: enabled sbk burned: false dk burned: false boot device: emmc operating mode: 3 device config strap: 0 device config fuse: 0 sdram config strap: 0 Sending generated BCT...533Mhz Done downloading bootloader -- load address: 0x88300000 entry point: 0x88300000 sending file: loader.nb0 - 65536/467360 bytes sent \ 467360/467360 bytes sent loader.nb0 sent successfully waiting for bootloader to initialize bootloader downloaded successfully ERROR: SerialNumber or ProductID lost Please enter(or scan) the 16 digit barcode label data:
I had no 16 digit code on the back of my T30 board, only Windows license number which obviously did not work. Accidentally I took a 16 digit number from my other board which is Apalis T30 (different form factor) and entered it manually. I used this serial: 0025110102927621 ← Apalis T30.
I got my flasher to work well and flashed WEC2013 on this Colibri T30 board.
Now my board does not work and when boots in debug messages I see that it is recognized as Apalis T30 which obviously has different pinout etc.
How to reset my Colibri T30 back to state with no serial or whatever (delete config) ?
How to restore back functionality and most important where to get Serial number of my Colibri board ?
