MSP430F5341: boot loader erased

Hi

When the boot code is erased? Have you erased the bootloader memory when programming the device? The bootloader address located in 0x001000-0x0017ff

The boot loader is erased after several days/wks/months of working correctly

Hi Avi,

Do you have any erase flash operation in your code to erase the BSL segments?

NO, Is there a protection against such erasure?

Hi Avi,

BSL memory can only be erased by segment and it needed to unlock protection to execute the erase operation.  All the BSL segments are erased?  How do you know the bsl is erased when working for a long time? All the BSL segments are erased?

Hi Allen,

The basic operation is a communication with my card.

When communication is lost, I try to load the firmware and I can not.

Only if i program the bootloader , I succeed to communicate.

It happens in a few cards(Not all of them), After Several days/weeks/Months.

I did not check if all the segments are erased.I just Reprogram the bootloader.

Hi Avi,

Can you post your code, I can review it to find if there is some clues.

Sry, I can not
