Tool/software:
Hello,
We are using your MSP430F249-EP microcontroller. During power on/off cycle MCU is sometimes not boot at power up. We have faced very rarely this issue generally (1 time in 200 attempts maybe in much more attempts). We are using 47k ohm res (VCC to RST line) and 2.2nf cap (RST lint to VSS) on RST line. When we increased cap value on reset line (2.2nf to 100nf) we have faced more this issue. Then we have changed res value (47k to 10k) and disassembled capacitor we have not faced boot problem (maybe the frequency of errors has decreased). We have checked MCU power it seems normal at start-up. We have tried adding delay after power up the frequency of errors has decreased but faced same issue. During test we are waiting 40-50s after power off. Can you give some advice for this issue? Where should we check? What could be the possible causes of the problem?
Thanks.
