Other Parts Discussed in Thread: MSP430FR6979, MSP430F449
Hello,
On some devices with MSP430FR6879 I get interrupt SYSSNIV Uncorrectable FRAM bit error.
But CRC above memory is fine.
So far discovered about 10 pieces from batch 1000 pcs.
The device uses LPM3 and 1 MHz MCLK
PMM29 is implemented.
//-------------------------------------------------------------------------
// FRAM
//-------------------------------------------------------------------------
FRCTL0 = FRCTLPW; // unlock FRAM control
// enable NMI correctable & uncorrectable bit error
// ERRATA PMM29 -> clear the FRLPMPWR
GCCTL0 = UBDIE + CBDIE + FRPWR + 0;
FRCTL0_H = 0; // lock FRAM control
In the past, MSP430FR6979 was used and the error never occurred.
Except this fault, everything else is fully functional.
Any idea ....
