CW 10.1 Debug - Unable to write Flash (USB TAP)

[Kafre]

Hello all,

I use Codewarrior 10 for MCU with MQX 3.6.2 and I'm flashing a M54452 Coldfire V4 MCU using USB TAP.

I'm currently trying to flash my MCU with no success. Every time I try to debug I get a signal halt exception: No source avaliable for 0x8000040A (that is indeed the MCU's SRAM direction). When I check that memory space using the Memory Browser, I see something loaded. I suppose that it is the internal program to load the FLASH and the SDRAM. The dissasembly shell points to the "rte" instruction, by the way.

If I try to read the content of the Flash using Memory Browser I get a buch of Fs. When reading the SDRAM I get 0s.  This means that both are empty but I don't get any error in the launching process and my .S19 and .XMAP files seem correct.

Anybody has a clue of what could I be doing wrong?

Thanks.

Hello again,

I'm triying to run my program using a direct aproach (launching directly the ttf task). I get this code: 

fl::target -lc "Flash_Debug"fl::target -b 0x80000000 0x8000fl::target -v on -l off -ie on -i "D:/workspace/LIBS/CCU.cw10/mqx/dbg/mcf54452.cfg" -p MCF54452cmdwin::fl::device -d "S29GL256N" -o "16Mx16x1" -a 0x0 0x1ffffffcmdwin::fl::image -f "D:\\workspace\\Shell_test\\CCU_Flash_Image_Debug\\Shell_test_Flash_d.elf" -t "Auto Detect" -re off -oe offcmdwin::fl::erase image Beginning Operation ...    ------------------------- Auto-detection is successful.

And goes on and on. It never stops programming!

Any idea?

This is what I get when I tipe "show cc" in the CW Connection Server:

Hello again,

My Flash was wrongly connected. I connected the Address 0 pin for a 16 bits addressable memory and as commented on the FAQ that will not work. 

I'm making a workaround using the Flash Tool Kit since I can't physically change the pin connection. I will create a new topic here about the FTK if I find it necessary.

Thank you very much.
