Hello,
We have a card based on TI's MSP430.
Upon powerup, the BSL reads 3 bytes from 0x1800. This is a customized BSL based on TI's original source for IAR.
If the pattern exists, the MSP430 stays in BSL mode.
If the pattern is 0xFFFFFF, MSP430 runs the application previously burned to 0x4400.
When the application runs we can write a pattern to 0x1800. After reset (or power up), the MSP430 should wake in BSL.
When we apply '0' to the RST pin of MSP430 and then '1' we noticed that the MSP430 restarts the application. It does not run the BSL.
If we shutdown the MSP and then turn it on, it runs the BSL.
Can you help ?
Thanks,
Zvika
