TMS320F28386D: Internal Oscillator configuration not working for TMS320f28386D

Hi Bandi,

Have you enabled the device_support option in the sysconfig tool for the clocktree changes to get reflected?

Also can you share the clocktree.h file generated by sysconfig ?

Can you share the DEVICE_SETCLOCK_CFG macro configuration in the device_init funciton, to confirm whether the program is correctly pointing to the clocktree.h for the macro defiinition.

//
// Set up PLL control and clock dividers
//
SysCtl_setClock(DEVICE_SETCLOCK_CFG);

Thanks

Aswin

Hello Aswin,

I am sharing the screen shot related to device support in sysconfig, Please guide me how can i enable the device_support option in the sysconfig tool for the clocktree changes to get reflected.

And also sharing the clocktree.h file generated for internal oscillator for TMS320F28386D

And also sharing the DEVICE_SETCLOCK_CFG macro configuration in the device_init funciton, to confirm whether the program is correctly pointing to the clocktree.h for the macro definition and also SysCtl_setClock(DEVICE_SETCLOCK_CFG);

If i click on the DEVICE_SETCLOCK_CFG it is displaying the clocktree.h content only

Finally sharing the  DEVICE_SETCLOCK_CFG macro configuration in the device_init funciton                                                     

Please refer and let me know for ant modifications required

Hello Aswin,

Could you please help me how to the device_support option in the sysconfig tool for the clocktree changes to get reflected.

And also if i remove the code related to XTAL then do i write and  add any function related to INTOSC1, as i am using the internal oscillator for TMS320F28386D (Custom Board).

I removed the below attached code, should i add any function to use internal oscillator?

Thanks & Regards

Bandi 

Hi Aswin,

               After all the above changes i am getting an error

Any suggestion what might causing this issue, i have been struggling this issue for 2 weeks. Can you please guide me how to resolve this

Thanks & regards

Bandi

Hi Bandi,

Have you tried restarting the board (power off and on) and tried again?

Did you make any configuration to run in low power mode?

Try creating a separate workspace, new target configuration and try again (Just to confirm if the workspace/target config has no issues)

Also do you face this issue while loading the program or is it while reading some register value?  And did you face it in all the devices available with you ?

Thanks

Aswin

Hello Aswin,

I tried restarting the board (power off and on) and tried again and again, also created a new project using new workspace still i am facing the error while loading the program

I tried with the UNIFLASH tool there also getting the same error

When i tried for multiple power off/ on and reset the power for board in between i am getting below error

Can you please help to come out of this issue

Thank & Regards

Bandi

Hi Bandi,

Are you able to connect your device? Is the issue coming when you are trying to load the program?

If you are able to connect to the device, i suggest you to erase the flash and try again loading.

Connect the target -> go to tools -> click On_chip flash  ->  go to erase flash option in the on-chip flash view

Thanks

Aswin

Hello Aswin,

Still I am unable to connect the device, I am facing below while loading the program

I tried to erase the flash using On_chip flash under TOOL, but unable to find the  On_chip flash option 

I tried using UNIFLASH tool also getting the same issue

Could you please suggest us why the device is behaving like this?

we were using TMS320F28386D device with custom board, it's been 3 weeks we were trying to flash the code into the target

Regards

Bandi

Hi Bandi,

I am assuming you have loaded some code in the FLASH configuration to have the device go into low power mode.

So everytime you try to connect the device, it will have this issue.

Please confirm if the board is powered properly.

I suggest you to update the boot configuration from BOOT from flash to other option in the emulation board. Look for the S1-A switch on the hardware.

S1:A - Emulation & GPIO28 Switch

POS 1 ON: Use xds100v2 emulator that is on the cCARD

POS 1 OFF: Boot from FLASH/peripheral (see boot mode switch) OR use emulator on baseboard

POS 2 ON: GPIO28 will be controlled by the USB-to-UART adapter on the FTDI chip

POS 2 OFF: GPIO28 can be controlled by a pin in HSEC connector

Currently the boot pin setting (POS 1) will be OFF, you can make it as ON (so that it doesn't boot from flash)

Then you should be able to connect to the device and you should be able to see the On-chip flash option in the tools menu. Then follow the steps in the previous reply.

Let me know if you are able to come out of the issue.

Thanks

Aswin

Hello Aswin,

I am glad to say that, now I am able to flash and run the code using RAM (CPU1_RAM) Module, but when i tried device is configured for boot to flash code using FLASH (CPU1_FLASH) getting the below error.

Could you please help me this?

Thanks 

Bandi

Hi Bandi,

Glad that you are able to load in RAM config.

Have you erased the flash as mentioned in the previous reply using the ON-chip flash option in the tools menu? if not can you do it ?

I think there is another program still residing in the FLASH, which is causing the issue.

Can you try to load the program in FLASH config disabling the boot to flash switch in the emulation board?

Set S1-A -> POS1 - ON and try loading to CPU1_FLASH config and see if you are able to load the program.

I am not sure if the example that you are using is provided in the C2000Ware SDK, if not can you try loading any existing example in the C2000Ware SDK.

Thanks

Aswin

Hello Aswin,

As you said i tried to erase the FLASH  using ON-CHIP on tools, Still facing the below error

I Set S1-A -> POS1 - ON and try loading to CPU1_FLASH configured, I could able to flash from TMS320F28388D (control card), here also when i TURN OFF power and TURN ON program is not staying forever(LED blink disappeared after reset) but not even loading from Flash_cpu1 (TMS320F28386D) from custom board.

could you please help me

Thanks & regards

Bandi

Hi Bandi,

Since the S1-A POS1 is set in ON position, it will not boot from flash. 

You need to make the switch to OFF position to make it run in standalone FLASH configuration after you do a TURN OFF and TURN ON.

So were you able to blink the led in CPU1_FLASH configuration?

Thanks
