Flash Error while programming F28M35 Concerto

Sandeep,

Is M3 connected to debugger and halted when you got this error on C28x?
What is the boot mode pin configuration used?

Thanks and regards,
Vamsi

Hello Vamsi

Yes the M3 is connected to the debugger and halted. I used the DSS Script to do this. 

However when i use CCS to halt the M3 and program the C28x, i do not get the error. 

Is there something wrong in the DSS Script then. 

Can i share the same with you to have a look?

Regards

Sandeep

Sandeep,

You can share the script.

What is the device revision?

What is the boot mode pin configuration used?

Thanks and regards,
Vamsi

Sandeep,

Do you still have this issue?

Thanks and regards,
Vamsi

Hello Vamsi
I am sorry for the delay in my reply. I was not actively looking into this issue as there was other issues which i was stuck with.
I am still getting this issue. It is not resolved yet.
Find below the file. I didnt know how to attach it as is so i have snipped it.

Thanks and Regards
Sandeep

Sandeep,

Will check the script.
What is the device revision?
What is the boot mode pin configuration used?

Thanks and regards,
Vamsi

Hi Vamsi

It is an experimental board. 

Boot mode pins are set to all 0's.

Regards

Sandeep

Sandeep,

Try these.

Open the M3 debug session first and then for C28x.

Connect to M3 first and reset M3.  Then Connect to C28x and reset C28x.

Also, try removing the resets.

If above does not help, try loading some code to M3 first and then to C28x.

Let me know how it goes.  

Make sure to check for CCS updates and install all of them.

Thanks and regards,

Vamsi 

Hi Vamsi,

I tried all the steps suggested by you.

For all the trials, I made sure I follow these steps:
1. Open the M3 debug session
2. Open the C28x debug session
3. Connect to M3
4. Reset M3 (I may or may not do this - to follow your suggestion)
5. Connect to C28x
6. Reset C28x (I may or may not do this - to follow your suggestion)

Exp1:
1. Reset M3 and C28x
2. Load the program to C28x

I observed the error

Exp2:
1. Do not reset M3 and C28x
2. Load the program to C28x

I observed the error.

Exp3:
1. Do not reset M3 and C28x
2. Load a program to M3
3. Load a program to C28x

For the very first time I did this experiment, loading program to M3 failed. I got the following error.
SEVERE: Cortex_M3_0: Error occurred during flash operation: Timed out waiting for target to halt while executing erasew.alg
SEVERE: Cortex_M3_0: Trouble Removing Breakpoint with the Action "Remain Halted" at 0x20004744: (Error -2044 @ 0x96) Internal error: Requested breakpoint does not exist. Restart the application. If error persists, please report the error. (Emulation package 6.0.222.0)
SEVERE: Cortex_M3_0: Flash Programmer: Error erasing Sector N. Operation Cancelled.
SEVERE: Cortex_M3_0: File Loader: Memory write failed: Unknown error
SEVERE: Cortex_M3_0: GEL: File:

I have made the script to exit in case of any error so it did not load the C28x program. From the second time onwards, irrespective of whether I power off and power on the board, I never observed this error for M3.

However, during the power off and power on cycle, even if the program load is successful for M3, it is not successful for C28x. I still get the error.
SEVERE: C28xx_0: Error occurred during flash operation: Timed out waiting for target to halt while executing pwrite_en.alg
SEVERE: C28xx_0: Flash operation timed out waiting for the algorithm to complete. Operation cancelled.

Exp4:
1. Reset M3 and C28x
2. Load a program to M3
3. Load a program to C28x

I still observe the error.

I would like to mention again that, while I am working with CCS, just connecting the M3 is fixing this issue. So i just have to connect to M3 and then if I load the program to C28x it works. I am facing this issue only with dss.

I have pasted the script for your reference.

The error while loading program to M3 occurs sporadically.

Sandeep,

Can you try inserting the unlock sequence before loading the code?

Thanks and regards,

Vamsi

Hello Vamsi
What is an unlock sequence?
Regards
Sandeep

Hi Sandeep,

Please refer "1.10.3.2 CSM Password Match Flow" in device TRM to know how to unlock the device. This is only needed if you have security enabled by programming the password values in flash at password locations. If not then this step should not be needed.

Regards,

Vivek Singh

Hello Vamsi/Vivek
Then my original thread then remains unanswered on why that pwrite_en.alg error could come up.
Regards
Sandeep

I would also like to mention that this error happens with only F28M35x and with the same script file as mentioned above, this issue is not reproducible with F28M36x.
Is there something specific to F28M35x which we are perhaps missing.
Regards
Sandeep

Sandeep,

We are able to program C28x in F28M35x successfully using your script.

To help debug further, I asked our tools team to generate logs for GUI operation and script operation and compare them to see if there is any difference between the two in terms of initialization or sequence of steps. They will try that next week after the long weekend.

Device revision info will be present on the package (like YFB or YFC). Can you tell what is there on your device?

What is the PLL config that you are using to program C28x?

Thanks and regards,
Vamsi

Sandeep,

Any update on this?
Can you tell the device revision and the PLL config that you are using?

Thanks and regards,
Vamsi

Hello Vamsi

Yeah we are still facing this issue. 

The device is an experimental board. Can you let me know how to check the PLL Configuration. 

I am unsure about this. 

Regards

Sandeep

Sandeep,

Any update on this?
