F28377D loading flash program into CPU2 only

Raghuchandar Rajula

Other Parts Discussed in Thread: TMS320F28377D

I am using TMS320F28377D controller. CPU1 is used for main application of power controlling, whereas the CPU2 is used to communicate with other interfaces.

Here I need to maintain different codes for two CPUs. For example, if I want to change code only in CPU2, then it needs to put CPU1 also in debug mode, if I want to make it with CCS. Is there any process of loading program into only CPU2, without CPU1...?

Thanks in advance.

Hi Raghu,

If you are using CCS plug-in to load then code then you have to halt the CPU1 (put it in debug mode). This is becasue plug-in code gets loaded in to GSxRAMs which are owned by CPU1 and only CPU1 can change the ownership to CPU2. For this CPU1 need to be halted and then change the register setting through the JTAG access.

Thank you for your reply.

But I wanted to know that if it is possible or not by any means...

Hi Raghu,

For CCS plug-in there is no other mean and since CPU2 is kind of slave core on this device, CPU1 interaction will be needed even if someone want to have their own BOOTLOADER.
