I'm programming Flash Loader IAP for uPSD3200 family chip .

In the VM registerthe configuration is for Boot_Code and Flash_Data.

I succeed to erase and write all the sectors in the main flash .All the sectors of the main flash reside in addresses 0x8000-0xFFFF .

My problem is that i can not erase or write to the secondary flash (32k)-flash boot which is the common area .

When i'm using the upload option of the JTAG FlashLink in the PSDsoft Express and dumping the flash boot into a file i see at the beginning of the file the following intel-hex format record :

:020000024000BC

Which means that the flash boot resides in addresses of 0x40000-0x4FFFF .

Is that correct?

How do i access the flash boot addresses for erase and re-program?
