How to update firmware on rt1064 running sbl single image OTA via ISP

[fsimz]

Hi, my goal is to run a bootloader on my 1064 and be able to update firmware without having to switch the board SW7 to serial download mode every time.

I have built the sbl binary from the github project and loaded it into flash at 0x70000000 using the flash programmer tool. The sbl configuration is single image OTA and ISP enabled.

As I understand it this allows the loading of the firmware via a serial connection using blhost while the board is in ISP mode after restarting.

I have tried writing the binary while in ISP mode to both 0x70100000 and 0x70200000 using

blhost -u 0x15A2,0x0073 -j -- write-memory 0x70200000 fw.bin 0

and while the write appears to be successful, I cant get the firmware to work.  I'm not sure what i'm doing wrong. Any help would be really appreciated.

Many thanks,

Fabio
