AM3359: RTOS PRU compilation warning

Unfortunately, I cannot build the source code in the attached .7z file.  This ...

Garrett Ding said:

C:\ti\pdk_am335x_1_0_10\packages\ti\drv\icss_emac>gmake >icss_emac_warning.txt

... implies the presence of a makefile.  But I don't see one.

Rather than send in a makefile, I'd appreciate if you would show exactly how the compiler invoked to build one of the problem assembly files.

Thanks and regards,

George,

Thanks for looking into this. Here is build process for the emac_MII_Xmt.asm:

Regards, Garrett

One of your include paths is ...

-I/ti/PD2F83~1/packages/ti/drv/icss_emac/firmware/icss_dualemac/src

I don't recognize it.  I tried building without it.  As expected, it failed.  This is probably a path into a software package I don't have.  Please send me a link to it, and indicate what version to use.

Thanks and regards,

George,

The short directory name is pdk_am335x_1_0_10 which is from Processor SDK RTOS for AM335x - 

http://software-dl.ti.com/processor-sdk-rtos/esd/AM335X/latest/index_FDS.html

The PDK driver build instruction is available here -

http://processors.wiki.ti.com/index.php/Rebuilding_The_PDK

Essentially, you need to run pdksetupenv.bat in pdk_[soc]_[version]\packages\, then go to the driver directory packages/ti/drv/icss_emac and run 'gmake clean' and 'gmake'

Thanks,

Garrett

George,

The matching .endif is at the end of the file emac_MII_Xmt.asm. There are 75 .if and .endif in the file.

If adding one more .endif, I got the error:

"src/emac_MII_Xmt.asm", ERROR!   at line 929: [E0006] No matching .if specified

               .endif

1 Assembly Error, No Assembly Warnings

Errors in Source - Assembler Aborted

Can you please continue to look into the issue?

Thanks, Garrett

Then we are not looking at the same file.  I get it from the src.7z archive you attached to the first post.  Here is what I see ...

$ grep '\.if' emac_MII_Xmt.asm  | wc -l
76
$ grep '\.endif' emac_MII_Xmt.asm  | wc -l
75

Thanks and regards,

-George

George,

I think the .if in the comment below is counted by the grep.

' ;Check whether we have transmitted all the bytes ..if not than call Tx Task again for this packet'

Garrett
