TMS320F28P650SH: problem of download

Hi,

Please refer to Table 3-8 in the F28P65x Flash API guide to debug. It looks like you're attempting to double write to an address.

if i use Code Composer Studio 12.4.0,the download can successful. only 12.81 has problems

Hi,

Can you confirm if the issue persists on CCS v20? There may have been a change to the flash plugin in v12.8.1 that is causing issues.

Best,

Matt

v12.8.0 is ok,V20 is too different,It's very difficult for me to know how to use it

Hi,

Apologies, TI will no longer be updating CCS v12 and will only be supporting v20 going forward. If you want to use v12.8.1, you can copy over the working flash plugin files from v12.8.0: 

1. In ccs1281\ccs\ccs_base\c2000\nowFlash\configs, replace the following flash configuration xml’s with the updated files from CCS v12.8.0
   1. nowFlashConfig.xml
   2. NowFlashLibraries.xml
   3. TMS320F28P65x.xml
   4. TMS320F28P65x.CPU1.xml
   5. TMS320F28P65x.CPU2.xml
2. Run fsclean.bat (ccs1281\ccs\ccs_base\common\bin)

ok ,i will try it next week,thank

Hi,

Sounds good, I'll close this thread now that the root cause has been identified.

Matt

Still the same problem

The contents in these five files are the same,whether it is v12.8.0 or v12.81

Hi C,

Let me check in with other experts and get back to you.

Hi,

Coils you please verify if all the flash banks used belong to CPU1 for the example you are trying to load? This error seems to be related to this.

How to verify 

Hi,

You'll want to verify that DEV_CFG_REGS.BANKMUXSEL is configured correctly by CPU1 (CPU2 can only read this register).

Aishwarya

I've tried, but it didn't work.

And TMS32F28P650SH6 doesn't have CPU2

Hello,

Could you share your linker file? I am currently unable to replicate this issue using CCS 12.8.1.

Could you also try erasing the entire flash before loading your program?

Best,

Alex

i also select Entire Flash,the problem is same.linker file is .out?

I have solved the problem of CCS 12.8.0，so i  not going to use 12.81,I will use 12.8.0

Thank you very much.
