5.001 Beta - Problem of "write_program_memory" (SO

[naughty_mark]

Hi, All
Recently, I met a kind of problem when I use my bootloader on dsPIC33EP256MU814 and my compiler version is 5.001 for bootloader code, and version 4.133 to compile main program.

The problem is with same bootloader code in microchip, when I try to send hex file through RS232, sometimes the microcontroller stuck after a while. It wrote several bytes for example 51200Bytes, then for the next write(for example when it tries from address 0xC800(virtual address, twice of physical address)), it stuck and will be reset because of watchdog.

However, some of hex file won’t have this problem with the same bootloader code.

Anyone suffer this kind of problem before?

Thanks a lot
Mark

I don't use ds33 PICS or the new compiler but...

Does your bootloader and main program work 100% every time if both are compiled with v4.133?
By 100% , I mean at least 20 tests with no problems on at least 3 different PICs?

If so, why 'upgrade' to v5.001?
Unless there is a new feature that you must have,you should stay with what you know is a reliable version of the compiler.

Hi, guys.

I debug deeper of my code, and found there is a bug to cause that problem, and now it is OK. Stupid me

Thanks for you guys attention.

Kind Regards
