#147633 - We've fixed it Responding to: ???'s previous message |
Thanks - I hadn't added the required line to assembler to enable the xdata. I had enabled it in c (as the first line of my main method) but this was too late. The compiler was trying to put the variables into xdata before it was initialised - these were then overwritten with code
The crucial line: ORL PMR,#1 ;PMR.DME0=1 (set to 1 to enable SRAM) |
