Upload of Bootloader fails

[Jenzo]

We are trying to upload Bootloader only, but it fails with 'Error 5: FW version check failed'. Please view log / pictures.

We have tried to change the bootloader version but it does not help.

What else could be the reason for the error?

Hi,

Do you know what bootloader version you currently have on the device? If not, is it possible to attach a debugger to this device and read the version number from flash?

The new bootloader must have a version number that is higher than the previous version. Otherwise you will get the FW version error shown in the log you posted above.

Best regards,

Vidar

Yes, that is correct. But can this be the only cause for the error? 

[Vidar Berg]

I don't see any other reasons for this error. Have you verified that the new bootloader update actually has a higher version number?

[Jenzo]

OK. Problem solved. I chose the same No as previous. 

My bad. 

Thanks a lot for a quick answer!!

No problem. Thank you for confirming the solution!
