Hello

I built the same project using two pc, but the two output files are different, and also .map files are different

Computer A is running win7 and CCS8.3.1
Computer B is running win10 and CCS8.3.1

I zip the project on ComputerA , copy to computerB and use "import CCS project" on ComputerB

I triple check that CCS version are the same, all libraries are the same, compiler is the same, platform is the same.

In the map file
- the ENTRY POINT SYMBOL is different
- the amount of used MSMCSRAM is different
- the length of the .text section is different
- input section have different origin address
- output section have different address

As result, the exe from computerA boots correctly from flash (on EVMK2H), the exe from computerB doesnt
Both version run correctly using JTAG

obviously I was expected to have the same .out using 2 computers.

Am I missing something?

I do not know what has happened. But I know a method to help you narrow down the cause of the problem.

The article Find Source of Code Size Increase shows how to determine which functions have increased in code size the most. Follow the same method, except that you are interested in any function with a different size. Focus your investigation on those functions. I do not know what you will find. But, whatever it is, it is likely to lead you to the root cause of the problem.

Please let us know what you find.

Thanks and regards,

using utility 'ofd6x.exe' I found size differences in function such as

pciev0_write_accr_reg 108 88 20
pciev0_write_ackFreq_reg 120 116 4
pciev0_write_capPtr_reg 32 24 8
pciev0_write_cfgTrans_reg 96 84 12
pciev0_write_cmdStatus_reg 120 108 12
pciev0_write_corErrMask_reg 140 116 24
pciev0_write_corErr_reg 140 116 24
pciev0_write_devStatCtrl_reg 316 252 64
pciev0_write_deviceCap_reg 160 136 24

Using utility winmerge I found that a lot of .se66 files inside directory 'C:\ti\pdk_k2hk_4_0_15' are different . For example

File \pdk_k2hk_4_0_15\packages\ti\drv\srio\lib\k2h\c66\obj\src\srio_drv.se66, line 130

COMPUTER_A , line 130

; gSrioDriverVersionStr[33] @ 264
.bits 0x4a,8
; gSrioDriverVersionStr[34] @ 272
.bits 0x75,8
; gSrioDriverVersionStr[35] @ 280
.bits 0x6e,8
; gSrioDriverVersionStr[36] @ 288
.bits 0x20,8
; gSrioDriverVersionStr[37] @ 296
.bits 0x20,8

COMPUTER_B, line 130

; gSrioDriverVersionStr[33] @ 264
.bits 0x4d,8
; gSrioDriverVersionStr[34] @ 272
.bits 0x61,8
; gSrioDriverVersionStr[35] @ 280
.bits 0x72,8
; gSrioDriverVersionStr[36] @ 288
.bits 0x20,8
; gSrioDriverVersionStr[37] @ 296
.bits 0x31,8

It seems to me that SRIO DRIVER version is different

The same happens with
file '\pdk_k2hk_4_0_15\packages\ti\drv\cppi\lib\c66\obj\src\cppi_drv.se66'
file '\pdk_k2hk_4_0_15\\packages\ti\drv\hyplnk\lib\c66\obj\src\hyplnk.se66'

see following figure, how many .se66

Anyway, I copied 'C:\ti\pdk_k2hk_4_0_15' from ComputerA to ComputerB, and now output files and map files are equal.

But really I dont understand why pdk directories are different.

Sounds like TEXAS released two different 'pdk_k2hk_4_0_15' ???

Fabio,

I don't think we published two versions of pdk_k2hk_4_0_15. The latest is here:

it should be PDK 4.0.16. The previous one should be here:

This is the PDK 4.0.15 you are using. It looks that on both PCs you downloaded the PRSDK installer but the contents are different. Do you still have both installer and the MD5 the same?

I am not sure what happened and glad you copied over and resolved the issue anyway.
