Sys/Bios boot from flash on TMS320F28035

Other Parts Discussed in Thread: TMS320F28035, SYSBIOS

Hi everybody,

I want to update DSP/BIOS to Sys/Bios on TMS320F28035, but I don't know how to edit link file. Can you send me a Sys/Bios project example booting from flash on TMS320F28035 ?

Thanks!

Sorry, I don't have a SYSBIOS project that boots from flash. Typically BIOS examples are built for RAM, then users take this example and make there own that works from flash.

There seems to be two different things you are trying to tackle here:

1. Moving from DSP/BIOS to SYS/BIOS.

2. Booting from FLASH.

For #1, I assume you have a working DSP/BIOS project that boots from flash? First, I would just try to port it over to SYSBIOS. If its easier to test in RAM, then do that first. Once you have a working example, then try to get it to work from flash.

For #2, I see some forum posts which someone ask how to do this: http://e2e.ti.com/support/microcontrollers/tms320c2000_32-bit_real-time_mcus/f/171/t/145791.aspx

Hi Judah,

Thank you for reply. As we know, DSP/Bios can configure memory section in .tcf file. However, we have to add a link file of .cmd to configure memory secton for Sys/Bios, and I failed to find example link file of .cmd in ti.com.

Best regards,

Hi,

Are you looking for a generated linker command file from SYSBIOS? These are named *.xdl

For SYSBIOS, the memory maps are defined in a Platform under the xdctools. Something like:

C:\ti\ccs5.1.0.09000\xdctools_3_23_03_53\packages\ti\platforms\control28035
