How to program QSPI from CW (flash program tool) on LS1020AIOT board ?

[dhruvalkumarpat]

Hi All,

I have erased QSPI flash on LS1020AIOT board completely and trying to program it again using CW flash programming tool . I was able to program both RCW and u-boot.bin. When I dump the memory I can see the RCW and u-boot program.

I flashed rcw at address 0x40000000 and u-boot.bin at 0x40010000 but I don't see any thing on UART . Is there any thing I am missing or is there any document mentioning how to program QSPI flash using CW flash programming tool. Once I get this working I want to repeat this procedure on our custom board using LS1020A .

Thanks

It worked . I was using windows and needed a special driver for embed to get to a com port  and that was blocking me to get to a serial port . following is a link to embed driver for windows in case someone having same issue.

The addresses looks fine. Did you use swapped rcw and uboot?
