LP-MSP430FR2476: Firmware Program doesn't execute after flashing through uart(BSL)

Hello Pallavi,

1). Firstly, check whether the address of your application and the address pointed by the  TI_MSPBoot_APPMGR_JUMPTOAPP() is same;

2). Secondly, read the Flash data out and compare it with the code you want to update, check whether the code updated into FLASH is correct;

3). Thirdly, I will be out of office until 14th April, if you have any other issue, I will help you after I back to office. And if your issue is urgent, you can set a new post, and our American colleague will help you in 24 hours.

Best Regards,

Hi,
Thank you for the reply
1.  below is the updated .c file generated for application

0x80,0x00,0xCA,0xC4,0xFF,0x3F,0x03,0x43,0x80,0x00,0xC6,0xC4,};

const uint8_t App1_1[] = {
0x18,0xC4,};

const uint8_t App1_2[] = {
0x0E,0xC4,};

const uint8_t App1_3[] = {
0x02,0xC4,};

const uint8_t *App1_Ptr[4] = {
App1_0,
App1_1,
App1_2,
App1_3,
};


so the application code starts writing from location 0x00C402.
This is the macro defined in the program: #define TI_MSPBoot_APPMGR_JUMPTOAPP() {((void (*)()) _Appl_Reset_Vector) ();}
Appl reset vector from lnk_cmd file is 

/* Reserved Flash locations for Bootloader Area */
__Boot_Start = 0xf800; /* Boot flash */
__Boot_Reset = 0xFFFE; /* Boot reset vector */
__Boot_VectorTable = 0xFFA2; /* Boot vector table */
__Boot_SharedCallbacks_Len = 0x10; /* Length of shared callbacks (2 calls =4B(msp430) or 8B(msp43 ) */
__Boot_SharedCallbacks = 0xff70; /* Start of Shared callbacks */
_Appl_Vector_Start = 0xf7a2; /* Interrupt table */
/* Reserved Flash locations for Application Area */
_Appl_Checksum = (_Appl_Start); /* CRC16 of Application */
_Appl_Checksum_8 = (_Appl_Start+2); /* CRC8 of Application */
_Appl_Start_Memory = (_Appl_Start+3); /* Application Area */
_Appl_CRC_Size1 = (_Appl_End - _Appl_Start_Memory +1); /* Number of bytes in lower memory calculated for CRC */
_Appl_CRC_Size2 = (_Flex_End - _Flex_Start + 1); /* Number of bytes in upper memory calculated for CRC */

_Appl_Reset_Vector = (__Boot_Start - 2);

Either the addresses  are generated from tools.  Do i need to change the address of TI_MSPBoot_APPMGR_JUMPTOAPP()

2. Below is the data generated from .c file and being sent to target and i have checked with memory location. The data is written

Hello Pallavi,

1). You should ensure the TI_MSPBoot_APPMGR_JUMPTOAPP() can let pointer jump to the address of your application code;

2). I mean you should read out the Flash data after you complete the update, and compare the data in the FLASH with the data you want to write to Flash, and check whether they are same.

3). You can summarize your questions and test results, and set a new post, my American colleague will respond to you in 24 hours because I am going to catch the plane soon and can't reply to you in next few days.

Best Reagrds,

Ok thank you i will set a new post

OK Pallavi. I will close this thread now and hope you can resolve your issue soon and get a satisfactory answer.
