Hello

Wonder if you had a chance to look at the SBL or boot loader document on device page.

Please also check the driver for Qspi and how the code configures it.

We will provide follow up to this thread next week.

Please respond next week if you do not see a response.

Thank you

Vaibhav

I've looked at it, and now I need to port this part of the code to know which statement or which file controls the location of sBL.bin and the other bin file in Flash.

Hello,

The SBL.BIN is always placeed start at adress 0 of the QSPI flash. After 1642 power up, 1642 will try read the SBL image from address 0 in QSPI flash.

For the APP.bin, you can adjust the app.bin address to any adress if you want. What you need to do is modifiied the OFFSET address in SBL code to match the physical APP.BIN address in QSPI address.

Thanks,

Regards,

Wesley
