Other Parts Discussed in Thread: MSP430FR5043,
Hello!
We have built a project for the MSP430FR5043 ; it's an edited version of the example project from software-dl.ti.com/.../.
This project compiles, links and runs on the MSP430FR5043 without problems.
When I tried to run it on MSP430FR50431 by changing the target, it compiles, links and runs just the same as on 5043, but only until I cycle the power.
After the power cycle, the device begins to reset repeatedly. The debug showed that it's being reset by a watchdog timer firing, after the device gets stuck inside code = USS_runAlgorithmsFixedPoint(&gUssSWConfig,&algResFixed);
The function accepts two arguments; the first one describes the configuration and the second one contains the results of the previously conducted measurement. I have attempted to replace the actual measurements with values that I know are valid, to eliminate the number of unknowns in the problem; that didn't really affect anything.
Sometimes after the power cycle, the device stops working altogether, failing to even enter main. I suspect that the FRAM is getting corrupted, but I don't understand what's going on and why doesn't this affect the 5043 ?
Thank you very much for your generous support .
