Tool/software:
When using the TMS570LS3137 chip, the Bootloader is burned in the BANK0 area, and the application (App) is updated to the Mram area of the Emif interface. It is necessary to jump from the Bootloader to the Mram address to start the App. It is found that the APP cannot start normally.
1. Does TMS570LS3137 support jumping from the internal FLASH to the MRAM address outside the emif and executing the APP?
2. How to configure the bootloader to jump to the Mram address and run the app?
3. Please check if there is any problem with the following configuration, thanks.
<1> Bootloader jump app instruction：
#define APP_START_ADDRESS 0x60000000
g_ulTransferAddress = (uint32_t)APP_START_ADDRESS;
((void (*)(void))g_ulTransferAddress)();
