TMS320F28388D: Accessing CLB registers in CPU2

Hi Team,

As per the F2838x TRM, CLB registers can be accesses by both CPU1 and CPU2. However, when I tried the same in CCS, I was unable to access CLB registers in CPU2. Is this expected? I have attached the screenshots

I see. You should still be able to access the registers in code. Make sure to pass control of the CLB peripheral to CPU2 through CPU1.

For the missing registers in CPU2 in CCS registers window, you are correct that is missing. I will work with the CCS team to add this to the register view.

To select CPU for CLB, in DevCfgRegs.CPUSEL15 I can see CPU selection for CLB1-4. However I cannot see the same for CLB5-8. Which register will be used for these CLB tiles?

Although not mentioned in the TRM, I found it in the 'f2838x_sysctrl.h' file in latest C2000 version(C2000Ware_3_03_00_00). However, these details are missing in the 'f2838x_sysctrl.h' file C2000Ware version 3_02_00_00.

Thank you Nima for the answer earlier.
