TMS320F28P650DK: Clock configuration

Part Number: TMS320F28P650DK
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hello expert, previously this process could run on this board. Now I need to run it on the company's board. The chips are all 28p65, but the main frequency of the company's board is 200 MHz. It uses an external crystal oscillator, and the clock frequency is 20 MHz. I have currently made these modifications, but the process is running incorrectly as shown in Figure 1.

Figure 1.

The following are the modifications:

Figure2.

Figure 3

Could the expert please tell me if there's anything wrong? If we want to transfer the process to the development board, apart from the clock, are there any other things that need to be done?

    Hi Nie,

    I’ve used SysConfig (by enabling Device Support and excluding the device folder from the build) to set up the clock to 200 MHz for both the LaunchXL and a custom board — in my case, using a 10 MHz external oscillator, which is similar to your setup.

    You could try configuring the clock through SysConfig and then compare the generated code with yours to see what differences there are.

    From your code, it looks like DEVICE_SETCLOCK_CFG might be the source of the issue.

    Best regards,
    Sebastian

    Hi Nie,

    As Sebastian suggested, please use Sysconfig to configure clock settings for your LauncjPad.

    Regards,
