I am CodeWarrior 7.2 with MQX 3.6 along with a Tower MCF52259 CPU and TWRMEM card that contains a 512K MRAM.
The jumpers on the MCF52259 board and TWRMEM are set to default.
I am using the onboard Coldfire V2-V4 JM60 OSBDM debugger
I can build the Web_hvac_twrmc52259.mcp in codewarrior to int_flash_debug , erase and program the internal flash and debug the project without any problem.
If I build the project to ext_mram_debug the code is uploaded to the mram and the debugger is entered at __main.
I can single step lots of instructions but as soon as I enter RUN I get the message
GDI Protocol Plugin
"The debugger cannot read memory"
Can anyone help
