Hi. I have to do a IAP system for a uPSD 3433EV and I am researching for this. my memory map have the CSBOOT in common area (0x0000-0x7FFF) and FS sectors are blocks together to 4 pages of 32k each (i.e. FS0: 0x8000~0xBFFF, FS1: 0xC000~0xFFFF: FS2/FS3, FS4/FS5, FS6/FS7 are overlapped qith these addresses, like pages). I don´t know how what I need to do for have a IAP system in this configuration. Can you help me? Can you explain the memory map for your application?

thanks.

Hi everyone,

I want to transfer code form upsd3234 to upsd3454.In the IAP process, It couldn't work in the upsd3454, but it works in the upsd3234. I just set the VM register to 0x12, and it could jump to the csboot0, and do the IAP process in the upsd3234. So what did I lost something to do?

Thanks

Jerry :o
