Hello M3Guy, We have analyzed this and we have found 2 problems. The first one was a problem in the GDB Server which causes the flash download to be skipped.

The "monitor reset 0" should be done before the "load" command. Furthermore you should include "monitor endian little" to set the GDB server to little endian. Attached is the corrected G…

Hello Steve, J-Flash uses the .ini file to save the global settings and to remember the last project file used. In the case that you start two instances of J-Flash via commandline it is possible that both of them try to write to the .ini file at the same time to save the name of the project file. We will improve this behaviour in future releases. A good workaround for now is, to make a copy of the J-Flash folder and start the two instances from the different folders. This causes the two J-Flash …

Hi Mike, The MMU can be enabled / disabled by bit 0 of the CP15 control register (which is addressed with: CRn=1, CRm=0, op1=0, op2=0). You can use the GDB Server to read out the current value of the control register and to write back a modified value. The sequence below shows how to disable and enable the MMU on an Atmel AT91SAM9260. We have configured the MMU to map SDRAM @ 0x40000000 which was normally address of the NAND flash. As you can see, we disable the MMU and we read NAND flash (which…
