CODECOMPOSER: CCS3.x to CCS12 migration - BIOS issue

Hello Adrien

What device are you developing for?

Unfortunately we no longer support SYSBIOS/ DSP BIOS etc and there are no expertise in the team to field this query. We had asked internally but did not find any good guidance.

The only collateral/content i can point you to is the following appnote

This is also a bit dated, but may have other tips and tricks

Hello,

I am using an F2810.

My client is using this old (and expensive) part, and is afraid that their las computer with CCS3.3 might "give up", and they might not be able to manufacture their products. Migrating the toolchain to CCS12.5 was a first step in assuring manufacturability of their product. A second step would be to migrate the code to a new target, better and cheaper.

The only thing I could do is try to migrate DSP/BIOS to SYS/BIOS and see what happens, but I am not sure I want to go down this rabbit trail.

I will also check if Uniflash can solve the "programming in case of old computer failure" issue, even though it might not be fully satisfactory for the client...

Hello Adrien

I am going to redirect this post to our sister product line applications who manages F2810 support, will see if they have additional guidance on this.

Mukul 

Hello Mukul,

Thanks. Let me know if there are some updates from them.

Best regards,

Adrien

Hi Adrien,

Unfortunately, I can't offer much insight into how the DSP/BIOS build works and what may be causing this error either. I'm a bit more familiar with SYS/BIOS, but like Mukul said, we really aren't supporting either version of BIOS anymore. We're primarily recommending folks using BIOS to migrate to FreeRTOS (there's a C28x port of it in C2000Ware) if they can.

Hi Whitney,

Thanks for your feedback.

As I explained to Mukul, migration to FreeRTOS will probably be a second stage project, along with target migration. It doesn't make much sense, to migrate to FreeRTOS on an old part that doesn't support sysconfig at this stage. 

Thanks a lot for your help. 

According to the DSP/BIOS release notes, the last version of CCS it was tested with was v5. I'm not sure at what point BIOS support broke. It might be possible to find an older combination of CCS and compiler tools versions that are old enough to be compatible with BIOS, but new enough to work on a modern Windows 10 machine (or whatever OS you're working with)?
