Need to Update Bootloader but the board is in error mode accourding with the open sda manual in bootloader mode bliks 8 time wait for seconds and bliks back 8 time more and so on ..... is not allowing me to update OPEN SDA
see Bricking and Recovering OpenSDA Boards in Windows 8 and 10 | MCU on Eclipse for an explanation of that error code. It seems that you see the 'Application Error'. If you are using Windows 10 (see as well that article), the easiest way is to update the bootloader with a Windows 7 machine. Otherwise see the way discussed changing the Windows group policy.
I hope this helps,
