disable RST pin for some time in MSP430

Nitesh Padiyar77

I am working on TI RTOS based application for MSP430.

I have implemented the Firmware upgrade feature which will use TI Python tool to upgrade the Firmware.

Now on application jump to 0x1000(Boot Location) i am getting reset and its going back to main (0x4000) again due to our external Watch dog.

Can we disable the RESET pin for that moment ?.

Can we achieve using software handling i.e. control registers setting?

Any way to handler except hardware switch please suggest me

Thanks in advance

I suggest you post this question to the MSP430 microcontrollers forum:

e2e.ti.com/.../

As the reset vector is in flash, it isn't modifiable. Per the SYS/BIOS MSP430 boot up sequence described here:

processors.wiki.ti.com/.../BIOS_for_the_MSP430

you could add hooks in the startup sequence to redirect the flow if necessary.

Also, I found this link that may be helpful although it describes a non-RTOS based boot sequence:

processors.wiki.ti.com/.../Custom_MSP430_BSL
