Posted by Vien Nguyen Another dumb question here. Everyone knows that these flash chips could be erased/rewritten officially 100 times (practically maybe more). This is not a problem w/ production, but it's is a problem w/ debugging. By looking at the map file generated by the linker, when you link your appl. with the HMON for debugging, even though your appl. resides in RAM, but the HMON is still mapped to the on-chip Flash. Thus, it seems to me that everytime I run the debbuger, the chip will get erased and reflashed because of the HMON. Am I correct? I hope I am wrong here. Could someone shed some light here? How do you debug your appl? w/ or w/o using HMON? how do you configure or set up your debbuging session so that the on-chip flash is not touched everytime the debugger is launched? One more thing, it's about shawdow vectors. I've heard about that, and know that I have to use it in order to debug my appl in RAM, but I am not quite sure how to do it. Could someone please explain how to this, or give some guideline? Thank you all in advance, and I really appreciate your great help.

Hi all,
I am new here, so please bear with me.
I just bought a EDK2329 kit. Following the tutorial, I could repeat the tutorial quite well, except one small glitch. Once I have the kernel flashed on the chip in Boot mode successfully, sometimes I could not run the same tutorial in User mode, as instructed in the tutorial. If I switch the jumper CJ4-B as instructed, the debugger could not connect to the board at all. Could someone explain?
EDK2329 memory map is as follow:
0x00000 - 0x60000 : 384K of on-chip FLASH
0x80000 - 0xBFFFF : 256k x 16 external RAM
0xFF7C00 - 0xFFFBFF: 32K on-chip RAM
