mspm0g3507 flash use

You can read a specific flash address's value as below to read data at 0x1000 to variable buf

buf = *((uint8_t *) 0x1000);

Very thanks! but  when i use this "DL_FlashCTL_programMemoryFromRAM8WithECCGenerated()" fuction ,it doesn't save in theROM . if i start the program again will lose the previously saved . which function can make the data in ROM?  Thanks in advance!

The ROM can't be write it is read only memory!

You want to write something in flash, right? 

yes i wanna save little parameteres into the  flash

Thanks! i have successed ! thanks again

Hello 

The Ic is mspm0g1505 device , i can debug to test online. but it will not work when power off

How do you connect on PA18? For this pin is used for BSL invoke, if you do not use it as BSL invoke, you need to pull down this pin external or disable the BSL invoke function in nonmain flash

Disable_bsl_invoke_PA18.pdf

i have not use the bsl pin, and the bsl pin have been to gnd.

before i use the lp mspmog3507 development kit to verify code. now i change the mcu to mspm0g1505, i switch the ic ,the flash from 0x1000 to 0x3000 . but it will not work when i power off  

Have change the device from the sysconfig that will help you to include correct cmd file?

yes it can be worked debug online.

Do you mean it not work in free run mode, not power off, right?

under the debug mode , i can use it . 

but when i stop(red button),it still work ok, but when i plug in power again, it will not work.

You can try to disable the BSL invoke pin function as I mentioned above

I've tried it and it doesn't work, and this pin is always low

You can connect the device and read flash memory data by Uniflash to see if the code download into the flash correctly.

By the way, what's the SDK version do you use? And CCS version? For the debugger do you use XDS110?

Have try to download other demo code like C:\ti\mspm0_sdk_1_30_00_03\examples\nortos\LP_MSPM0G3507\driverlib\gpio_toggle_output (Need to change the device manually)

i can see the code from the code ,but it still can't be download 

If you can see the code in the flash area that means the code has been downloaded successfully. Can you share me the project you test now? And tell me how to monitor if it running or not.
