MSP432P4111: MSP432 custom bootloader

neetha prafa

Part Number: MSP432P4111

Hi all,

Our msp432 currently has two bin files residing in its memory. The first one being a boot bin file which switches to the main bin file located at a the memory location

0x00080000. The first bin file has the following instruction to initiate the switch which was borrowed from the steps mentioned in this link https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/535669 .

SCB->VTOR = 0x00080000;

__asm (

"mov r0, #0x0000\n"

"movt r0, #0x0008\n"

"ldr r1, [r0, #0]\n"

"mov sp, r1\n"

"ldr r1, [r0,#4]\n"

"blx r1\n"

);

I have attached the two linker scripts(0x800- 2bin file linker script, 0x00- 1st bin file linker script)i am using to build the target bin files for reference. The bin files are loaded via uniflash and for the second bin file the load address is specified as 0x00080000 on uniflash making sure the second bin file resides in the right location.

Could you please let me know how to start the execution of the second bin file we seem to be missing something in the assembly language instruction set.

Thanks,

Neetha.

I will hand on it later. Why do you need the customer BSL? Wht the original BSL can't meet your application?

Hi Gary,

MSP432 is accessible remotely, if we need to update an application we need to use UART only. If the update is bad we need to fall back on the original application that was present we need two bin files to be present on MSP432

Thanks,

Neetha.

Sorry for the late response. Have you take a look about the demo with MSP430 http://www.ti.com/lit/an/slaa600d/slaa600d.pdf?

Could you upload your code and make more details about your problem?
