Other Parts Discussed in Thread: CC2530

When download and debug a CC2530 application under IAR8051 8.20 with ZstachHome 1.2.0, I receive following warning. Why it is happening? Does it affect application function?

and after hitting OK it beings from 0x0000

Do you choose "Debug information for C-SPY" in Linker output of compile options and disable the following two lines in ota-boot.xcl?

-M(CODE)[(_CODEBANK_START+_FIRST_BANK_ADDR)-(_CODEBANK_END+_FIRST_BANK_ADDR)]*\
_NR_OF_BANKS+_FIRST_BANK_ADDR=0x8000

I added above two lines to ota-boot.xcl , it didn't compile and gives Linker error. _FIRST_BANK_ADDR is not defined.

I have this problem for application also. It's not only for boot loader.

I mean to comment out those two lines.

//-M(CODE)[(_CODEBANK_START+_FIRST_BANK_ADDR)-(_CODEBANK_END+_FIRST_BANK_ADDR)]*\
//_NR_OF_BANKS+_FIRST_BANK_ADDR=0x8000

By the way, do you set many breakpoints?

Thank you. It works for OAD boot now. But I have another Router Application that adding those 2 lines doesn't help. Breakpoint is set at main() but it gave the same warning.

Do you choose "Debug information for C-SPY" in Linker output of compile options? And also remember to check how many breakpoint you set.

Does it depend on how many breakpoints we set?

0 YiKai Chen over 11 years ago in reply to Arash Azarmi

Guru 735695 points

Yes. If I am correct, it will be safe to set less than 4 breakpoint sin IAR.

you are welcome! So, is your problem about setting too many breakpoints?

0 Arash Azarmi over 11 years ago in reply to YiKai Chen

Intellectual 885 points

I am not sure. I re-ran again and cleared all the breakpoints and it worked.

Yes, I think too many breakpoint are the root cause of your problem.
