MSP430F5418A: Questions on Bootloader

Siyou

Part Number: MSP430F5418A
Other Parts Discussed in Thread: MSP430F5438A

Hello,

I want to OTA upgrade the MSP430 firmware through wireless host CC1352, here I have some questions after studying the MSPBSL:

1, Due to the MSP430 available UART pins on my board are not P1.1 and P1.2, is it possible to change the BSL UART pins to P5.6 and P5.7 in customized bootloader?

2, If I invoke the BSL from MSP430 running application, can I skip the BSL entry sequence(by RST and TEST pins) in BSL host driver? We hope only use the UART Tx, Rx 2 pins for BSL UART protocol;

3, How to program the customized bootloader to MSP430?

4, How to access the BSL source code? The link MSPBSL_CustomBSL430 returns below error:

Hi Siyou, I will check the issue on the error link MSPBSL_CustomBSL430 and reply to you later. Thanks!

Hi Siyou,

The link MSPBSL_CustomBSL430 has been available.

Please check User’s Guide MSP430™ Flash Devices Bootloader (BSL), on flash device BSL

and please check https://www.ti.com/lit/an/slaa450g/slaa450g.pdf on 5xx/6xx and G2 device Custom Flash-Based Bootloader

Thanks!

Hi Xiaodong,

Thanks for updating the link, I can get the code now.

Could you also help confirm the question #1, we need to ensure our hardware design can meet the BSL requirements.

Aoording to SLAA450G, my understanding is the answer should be Yes, right?

Hi Siyou,

MSP430F5xx and MSP430F6xx devices ship with a standard TI BSL.

As the TI BSL programmed in Flash memory, the BSL can be reprogrammed and customized.

I think it is possible to change the BSL UART pins to P5.6 and P5.7 in customized bootloader on MSP430F5418A.

Thanks!

Hi Xiaodong,

I tried the customized BSL with UART P5.6 and P5.7 but failed, please review below procedures and point out what am I missing.

1, Modify the UART port pins to P5.6 and P5.7 in 《CCS_v7_MSP430F543xA_TA_UART》 project and then download it to device;

2, Download the test application to device, in this test application, it simply jump to BSL:

    void (* JumpToBSL)(void);
    __disable_interrupt(); // disable interrupts
    JumpToBSL = (void (*)())(0x1000);
    JumpToBSL(); // jump to BSL

3, Connect the P5.6 and P5.7 to PC serial tool with parameters “9600,8,1,even, none”. PC serial tool send GetBSLVersion command “80 01 00 19 E8 62” to device, but there is no any response from device UART.

Hi,

As described in https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/936966, I want to change the BSL UART pins to P5.6 and P5.7 but without luck, could you guide me how to achieve it?

Here are my test procedures:

1, Modify the UART port pins to P5.6 and P5.7 in 《CCS_v7_MSP430F543xA_TA_UART》 project, build and download it to device;

2, Download the test application to device, in this test application, it simply jump to BSL:

    __disable_interrupt(); // disable interrupts
    ((void (*)())0x1000)();

PS: I tried below two linker command files, both had the same result as step 3.

I guess the problem is <lnk_msp430f5418a.cmd> file was incorrect.

Is there any TI expert who can provide the <lnk_msp430f5418a.cmd> file for customizing MSP430F5418A bootloader?
