Part Number: MSP432P401M

Tool/software: Code Composer Studio

Hi ,

I have XDS 100V2 JTAG connector and i am using my own board for MSP432P401M.

I got this error during the debug process, error in loading the program:-

CORTEX_M4_0: Flash Programmer: Reading HW revision failed.
CORTEX_M4_0: Your XMS432P401R material is no longer supported. We recommend you moving to production-quality MSP432P401R/M silicon by ordering samples at www.ti.com/product/MSP432P401R.
CORTEX_M4_0: File Loader: Memory write failed: Unknown error
CORTEX_M4_0: GEL: File: C:\Users\Nikhil Bapat\workspace_v7\inclinometer1\Debug\inclinometer1.out: Load failed.

I already checked "MSP432 Launchpad Users Guide-Factory reset script" and its shows that my xds100v2 is successfully connected.

Please help me in solving this .

With regards

Sayali and I working together on this project.

Just to add something, the MSP432 board that we have designed used 48 MHz crystal. We started with example from the MSP ware and it was working. We were able to see the register values to reflect the voltage input at the ADC. When code for 48 MHz was added, this error started showing up. We tried it with two different computers and with different CCS versions but it is still the same.

Sayali,

I am curious since it is stated that the errors started when adding code for 48 MHz, have you changed also the flash wait states and Vcore? Please tell me if the information in this previous E2E post is of assistance: click here.

Hi Sayali, Nikhil,
The XMS432P401 is pre-production silicon, whose support has been discontinued since we now have the
production version MSP432P401R. See the link below for details on the differences.

processors.wiki.ti.com/.../XMS432_Support

If possible, I would recommend switching out the part on your custom board. (Yes, I know this can be
a pain, but it should save you many hassles going forward).

Regards,
Bob Landers

Bob,

The MCU that I have was ordered from TI directly and it says MSP432P401M Rev C.

That is the most intriguing thing. We are using the M version, not R. The linker and other files in the code are also for M and it was working before.

I am using CCSv 7. In Help->Installation Details, I can only see MSP432 tool-chain. I do not see MSP432 Emulators.

John,

When I added the code for 48 MHz I only added these lines to the main code:

// Configure DCO to 48MHz, ensure MCLK uses DCO as source

CS->KEY = CS_KEY_VAL ; // Unlock CS module for register access

CS->CTL0 = 0; // Reset tuning parameters

CS->CTL0 = CS_CTL0_DCORSEL_5; // Set DCO to 48MHz

CS->CTL1 = (CS->CTL1 & ~(CS_CTL1_SELM_MASK | CS_CTL1_DIVM_MASK)) | CS_CTL1_SELM_3; // Select MCLK = DCO, no divider

CS->KEY = 0; // Lock CS module from unintended accesses

I am attaching the main.c file here for reference.

Hi,

looks like you have the same issue as described in this thread.

It is important that the system is in VCORE1 and that the flash wait state is set to 1 in order for the device to work at 48Mhz.

When code with bad configured clocks is running in the device the debuggers have problems reading out the device information, thus leading to the described error.

Regards,

Thorsten

Nikhil,

It looks like you have not changed VCORE or Flash wait states. Since now I see you are using register level programming, can you please reference the following Example Code for setting up 48MHz DCO.

I think this should clear things up for you, but let me know if you have any further questions.

0 Bob Landers over 9 years ago in reply to Nikhil Bapat

TI__Expert 8510 points

OK, that is a bit odd, but at least you're using production silicon, so you don't have to worry about those differences.
From the rest of this thread, it looks like there are other issues as well. I think John is addressing the real issue at play here.
Let us know if you see the debugger error again after fixing the Vcore settings.

John,
I have imported the example code given by you.still it is showing same error while debugging. I am choosing a factory reset in msp432 setting and debug the code but error is same.I will have erase the code prepared by me. can you please tell me steps to erase the code??

0 sayali pathak over 9 years ago in reply to sayali pathak

Expert 1325 points

I am following the below steps to factory reset the launchpad

1. Connect the failing LaunchPad/unit to your PC.
2. Open CCS, assume you already have at least one MSP432 project open.
3. Go to View > Target Configuration.
4. Within Target Configuration navigate to your MSP432 project > the .ccxml file.
5. Right Click > Launch Configuration
6. Under Debug window you should now see some tree structure starting with the .ccmxl file being the root > something_CORTEX_M4_something (unknown)
7. Right Click > Show all hidden cores.
8. Connect only to the Non-Debuggable Devices > DAP.
9. Go to Script > Factory Reset.
10. Power cycle and try to restart debug.

My error is removed and now i successfully build and debug the " EXAMPLE CODE FOR SETTING UP 48MHz DCO".

TI__Intellectual 2405 points

Sayali,

This sounds like good news! Does this mean your issue is solved? Or are you still having troubles? Sounds like you got the example code to work. Were you also able to implement this in your own code?

0 sayali pathak over 9 years ago in reply to John P. Morrison

Expert 1325 points

Yes my issue is solved.I just add the following steps in my code to enable operation at MCLK=48MHz

1. Configure VCORE level to 1
2. Configure flash wait-state to 1
3. Configure DCO frequency to 48MHz

My code is also working without any error.

Thanks
