MSP430F5310: MSP430F5310 FIRMWARE UPGRADE USING ANOTHER MCU APPLICATION IS NOT GETTING RESET AFTER SOFT RESET SEQUENCE IN BSL CODE

with the  BSL code reset sequence  I am unable to exit from BSL

How do you do the reset?

here we have a mosfet in between MCU and reset pin of msp430 so giving inverted signal for reset. Same for test pin also due to the same reason.

GPIO_WritePinOutput(GPIO5,11U,1U);  // Test pin
GPIO_WritePinOutput(GPIO4,26U,0U);  //reset pin
MsDelay(200);

GPIO_WritePinOutput(GPIO4,26U,1U);// reset pin
usDelay(100);

GPIO_WritePinOutput(GPIO4,26U,0U);// reset pin
usDelay(100);

Please make sure the test pin keep to low when you do the reset. And have you try make longer delay to keep reset pin low?

Thanks for response. I am keeping test pin as low but in code you can see i am putting high it is because of a mosfet in between so ideally it is getting low signal. I have tried with different delay but do you want to suggest any specific time interval? 

Have you try the delay like 500ms?

tried with 300ms delay using  FreeRTOS tick...As I  said already tried with Reset vector and Load PC also but  undefined behaviour observed.. undefined behavior for example like LED blinking with high frequency...I am able to understand that it is due to the BSL clk settings change(8 Mhz) so tried to read Initial settings of my code for UCS registers and I have loaded in code in the start itself to avoid that undefined behavior ..I am  able to avoid that undefined behavior but some functionalities not working..so I want to know Is there anything I need configure in code apart from UCS register settings ?

Reset sequence will be most effective method I guess. Please let me know if you have any input for me?

Could you help to do a test that use an GPIO toggle demo code from MSP430F530x_P1_01.c (ti.com) and capture the reset pin, test pin, gpio toggle pin by a logic analyzer or oscilloscope? To see if any issue there.
