CCS/MSP432E401Y: Can not programm CCS CODE after LM FLASH with TI_TXT over USB DFU

Hi,

I sent it to a concerned engineer. We will get back to you ASAP. Please bear with us.

Thanks,

PM

OK, this has nothing to do with the TI TXT upload. The problem seems to be with the setup of BOOTCFG and start address mapping:

uint64_t bootcfg;

bootcfg = HWREG(FLASH_BOOTCFG);
if(bootcfg & FLASH_BOOTCFG_NW)
{
    HWREG(FLASH_FMA) = 0x75100000 ;
    HWREG(FLASH_FMD) = FLASH_BOOTCFG_PORT_B | FLASH_BOOTCFG_PIN_2 | FLASH_BOOTCFG_POL | FLASH_BOOTCFG_KEY | FLASH_BOOTCFG_DBG1;
    HWREG(FLASH_FMC) = FLASH_FMC_WRKEY | FLASH_FMC_COMT;
    while((HWREG(FLASH_FMC) & FLASH_FMC_COMT) == FLASH_FMC_COMT);
}

When I reset with my BL condition true, I can debug in CCS and i get 0x00002A12 in the BOOTCFG register but apparently can't change it.

so I tried the factory reset as desribed in slaa777a. I have to do it twice everytime I got this issue, but now I got a working Launchpad again.

But what did I do wrong with the BOOTCFG register, what is the right way to configure it?

With 

HWREG(FLASH_FMD) = 0xFFFF2AFE;

it`s working, so the missing 1s were part of the issue. Now everyting works, except TI_TXT loaded Firmware using the bootloader. And it doesn`t even matter if using UART or USB. It programms successfull and after setting ROM_BL Pin Condition back and reboot, the programm is not executed...

Thank you for that information.

Now I finally got a working USB DFU update with LM Flash and a bin File.

The BSL scripter successfully writes the TI_TXT fimware over USB DFU, but the program won't start.

If the BSL scripter is the tool to use, what am I doing wrong here?

Hello Dennis,

I pass this issue to the development team and ask them to respond once they figure out the issue.

Thanks,

Sai

Hello Dennis,

Can you send us the .txt and .bin files if possible?

Thanks,

Hello dennis,

I haven't tried your files, but this looks very similar to the issue in the following post: https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/837984

Can you confirm that you are noticing missing bytes when you read out Flash contents after firmware update?

Thanks,

Sai

Dennis,

Our development team is continuing to look into this issue.

Are you noticing missing bytes when you read out Flash contents after FW updates?

BR,
