CC2540: Bootloader cc254x_f256_sbl.xcl does not compile with IAR 10.40

LyChe

Part Number: CC2540

Tool/software:

BLE-CC254x-1.5.2.0

Update 6/19/2024 - When I comment out these lines, the error went away. Question - Why would these codes cause linking error?

//-Z(CODE)ALIGNED_CODE|2=_CODE_BEG-_CODE_END,_BANK1_BEG-_BANK1_END,_BANK2_BEG-_BANK2_END,\
//_BANK3_BEG-_BANK3_END,_BANK4_BEG-_BANK4_END,_BANK5_BEG-_BANK5_END,_BANK6_BEG-_BANK6_END,\
//_BANK7_BEG-_BANK7_END

I am seeing following error during linking when I use this linker configuration file: cc254x_f256_sbl.xcl.

Linking

Tool Internal Error:

Internal Error: In function: unknown

Diagnostic: unexpected exception

P0:1 P1:0

Error when running linker.

I don't see this error when I compile using IAR10.30.

I also don't see error when linking my project with other XCL file, for example ti_51ew_cc2540b.xcl.

Any idea how to fix this? Thanks.

Thank you for reaching out. According to the release notes, IAR v10.30.1 should be used. Using a newer version may result in unexpected behavior like you are observing. I would recommend using IAR v10.30.1 as this is what the SDK was tested with at release.

Best Regards,

Jan
