MSP432P401V: MSP432's firmware update over CC3200.

Thanks Sarah for your quick reply.

Now I want to know how I can create msp432p401_bootloader.c as it is there in example.

In the link above it is mentioned that there is a C array in msp432p401_bootloader.c that represents the compiled custom bootloader that resides in the top 32KB of the MSP432's memory. My query is how I can create this kind of file for bootloader from custom bootloader project.

Hi Keshav,

If you look in the following section (MSP432 Firmware Bootloader), it provides paths to the bootloader demo in the Wi-Fi plugin and an explanation of the flow: http://dev.ti.com/tirex/explore/node?node=AN7MIdvye8FP.yeGzQ4TJQ__s6qGmnm__LATEST

Hi Sarah,

I have already read that document. Although I'm following that as reference. But in that document it's not mentioned on How to make a C array representing a compiled custom bootloader.

I need to update custom bootloader project as per application and hence C array is also needed to be updated. Below is the example of a C array representing a compiled custom bootloader.

#if defined(__TI_COMPILER_VERSION__)
#pragma DATA_SECTION(ota_bootloader, "OAD_BSL")
#pragma RETAIN (ota_bootloader)
const unsigned char ota_bootloader[] =
#elif defined(__GNUC__)
const unsigned char __attribute__((section (".oad_bsl"))) ota_bootloader[] =
#elif defined(__IAR_SYSTEMS_ICC__)
#pragma location="OTA_BSL"
__root const unsigned char ota_bootloader[] = 
#endif
{
    0x00, 0x00, 0x01, 0x20, 0x7D, 0x68, 0x00, 0x00, 0x3B, 0x6C, 0x00, 0x00,
    0x39, 0x6C, 0x00, 0x00, 0x37, 0x6C, 0x00, 0x00, 0x33, 0x6C, 0x00, 0x00,
    0x37, 0x6C, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x37, 0x6C, 0x00, 0x00,
    0x37, 0x6C, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x37, 0x6C, 0x00, 0x00,
    0x37, 0x6C, 0x00, 0x00, 0x37, 0x6C, 0x00, 0x00, 0x37, 0x6C, 0x00, 0x00,

    ...
