Have a Cygnal F120 part with keil compiler and Bl51 linker. It has 8k xdata. The guy doing the hardware said he added 4k more for a total of 12k xdata. But I'm not sure how to access the other 4k. When I declare variables like normal and during linking the BL51 says xdata is greater than 8k, my program goes haywire. So I think there might be a special way to do this?
