I am writing a custom application that uses the MSP-GANG programmer for flashing MSP430F5341 chips, and another batch programmer for flashing other chips on the same target boards. I am able to successfully program the MSP430s, by creating an image in the MSP-Gang memory, and then calling the MSPGANG_MainProcess() function. I am using using MSP-Gang.dll version 1.01.00.00 (Oct 25, 2012).
So, my question: How can I toggle (not cycle) the target devices' Reset lines for an arbitrary length of time? (If any TI reps are reading, I did ask about this, but have not yet heard back--SR# 1-881 749 754.)
On each target board, the MSP430 chip controls the programming lines for the other chip, such that in order to program the other chip from an external source, the MSP430 must be held in reset. So what I want to do is to be able to issue a command (which?) to the MSP-Gang that holds the MSP430s' Reset pins low indefinitely. Then I will program the other chips; then I will send another command (which?) to the MSP-Gang to release the MSP430s' Reset lines.
I was thinking maybe the MSPGANG_SetTmpGANG_Config() function with CFG_TMP_RESET would do what I'm looking for, but so far that command does nothing by itself, even though it reports ERR_NONE.
Thanks for any help you can offer.
