Problems to upload Hex file to CC2530F256

This has to do with how the linker treats the extended addresses when using banked code model for the 8051 architecture. You will need to remap the addresses to make this work. But this is really simple. just open the linker file (you'll find it in the project under the "Tools" group and the file is called f8w2530.xcl).

Just scroll down and un-comment the two lines where it says "Include these two lines when generating a .hex file for banked code model:"

You can leave the two lines un-commented also when you're not making HEX files (at least if you're using IAR EW8051 v7.51A or later), but you will always get a linker warning. This workning can be ignored. You can actually turn it off by adding the following line to the linker file:

-ww69=i

A few more details: The -M option is needed when linker output should be in the "intel-extended" (HEX) file format for banked code model. It translates the logical addresses used by EW8051/XLINK linker to the correct physical flash addresses used in output file format. (Without this, the HEX output file will include 32 kB blocks of empty space/gaps in between each code bank, and our HEX image will not work.)
