Hello, My customer has problem with flashing FRAM in MSP430FR5739 by Lite FET-Pro430 Elprotronic. MSP430FR5739 is on customboard, the Fail occurs on some board (not all). Details of operation is following. It seems like it fails at "ERASE FLASH" and "BLANK CHECK". But when doing "ERASE FLASH" after Fail, it goes well. And do the "AUTO PROG" after "ERASE FLASH", it goes well too. After some trials, my customer found 3 good ways. 1) "AUTO PROG" without "BLANK CHECK", this works fine. 2) "AUTO PROG" after "ERASE FLASH", this works fine too. 3) Only do "WRITE FLASH", this works fine too. And the device( MSP430FR5739 ) which has been flashed well once, it would be flashed wuthout no Fails after that. Do you know what the cause is ? Regards, Takeshi Matsuzaki
