Need fix for linking error using TWR-KV58F220M support code?

erskineb · ‎05-23-2016

Hi, I am having a linking error with the SDK_1.3_TWR-KV58F220M.zip software package that supports the TWR-KV58F220M eval board.

I am using IAR Version 7.60 and the latest supporting files.

I have the following part selection in the project options, Freescale MKV58F1M0xxx24. but have tried all the parts listed for the KV5x device with the same results.

My debugger is the IAR I-Jet.

This error is occurring while compiling the example code without any changes to the original code.

The result is the same regardless of which of the example programs are selected.

The error is as follows:

Linking

Error[Li005]: no definition for "main" [referenced from cmain.o(rt7M_tl.a)]

Error while running Linker

Total number of errors: 1

Total number of warnings: 0

This same error was listed as a false error in an earlier version of IAR, but was indicated as fixed in the next release, so in short I have some question as to whether this is an actual failure.

In Project Options if I change the output from Executable to Library it goes through the compile process with no errors. But of course this should be the case because the linker is not executed.

My question is does anyone have experience resolving this error?

The following is the lower portion of the map file.

Thanks for your help,

Erskine Barbour

Hello Erskine.

I tested on my side and it works without any issue.

Ok. I need to get closer to your issue and need some additional information from you.

Please, I need to know:

what example did you compile?
did you try the example also in KDS? do you have the error also in KDS?
did you correctly set linker?

did you try clean project and built again?

Please let me know.

Best Regards,

Iva

Hi, Thanks for your response. I apologize for my reply beingslow. Your response indicated to me that all worked for you, so theproblem had to be on my end. First, I deleted all SDK_1.3_TWR-KV58F220M and reinstalledit. Second, I started over with the factory settings in IAR. Next added in the correct KV58x CPU in project options.Next, I compiled the Hello World Code.This time to my surprise it all compiled and linked.Then I added the I-Jet debugger and got the:Error[Li005]: no definition for "main" I remember updating the I-Jet when I updated to IAR 7.60.2and it worked on my other projects (KE02x based), but I reinstalled it againand it worked. So the root cause of my issue was the I-Jet. I do not know ifthe issue was an I-Jet option selected or the I-Jet driver itself. The first time, several weeks ago, when I had the error Ihad installed the I-Jet before I compiled SDK_1.3_TWR-KV58F220M code and thatwas the mistake. The error no definitionfor "main" linking error did not seem like a debugger error. It must be that this error is the default casein a switch statement when nothing else fits. One would most likely question why I even had an I-Jet becausethe eval board has a built in flashing/debug function, but the project I aminvolved in is not motor control, or USB connectivity, but an application thatneeds the high resolution, very fast AtoDs employed by the KV5x family. Theeval is just to get an early start on the first pass of the board and the boardunderdevelopment will use the standard Jtag type connector, which is on theeval board. Thanks for your help. Best regards,Erskine Barbour Will you please place this email in the forum, thanks again?
