MSP430F5435A: Segment B corruption

Thib

Part Number: MSP430F5435A

Hello,

I have Segment B corruption on around 50 Msp430F5435A (rev F and rev H). All the segments B are written with 0xFF. For these msp I have several SVSH and SVSL resets type. Do you know which could cause this corruption. The msp are powered by a battery.

It's critical because I store a CRC in this flash area.

Thank you for your help.

Hello,

I would say that this issue is caused by errata FLASH37, but according to the erratasheet, it does not affect Rev. F or Rev. H devices. Does this behavior happen on other revisions of the same device?

Regards,

James

I have only rev F or rev H. I read the errata sheet but I didn't see anything which could explain this behavior.
