Tool/software:
Hi Team
Iam trying to do custom firmware upgrade via ethernet bootloader code by partitioning the FLASH for custom bootloader and custom Application
The problem iam facing is
Non RTOS Application are working and booting properly after Firmware upgrade
Whereas using RTOS based application in firmware upgrade , It get stuck in switch address function mentioned below
void SwitchAddress(uint32_t StartAddress)
{
UARTprintf("Start at %x\n",StartAddress);
IntDisable(INT_TIMER0A);
IntDisable(INT_TIMER1A);
IntDisable(INT_TIMER2A);
IntDisable(INT_EMAC0);
IntDisable(FAULT_SYSTICK);
IntDisable(FAULT_NMI);
IntDisable(FAULT_HARD);
//
// Disable all processor interrupts. Instead of disabling them
// one at a time, a direct write to NVIC is done to disable all
// peripheral interrupts.
//
HWREG(NVIC_DIS0) = 0xffffffff;
HWREG(NVIC_DIS1) = 0xffffffff;
HWREG(NVIC_DIS2) = 0xffffffff;
HWREG(NVIC_DIS3) = 0xffffffff;
HWREG(NVIC_VTABLE) = StartAddress;
// Load the stack pointer from the application's vector table.
__asm(" ldr r1, [r0]\n"
" mov sp, r1");
// Load the initial PC from the application's vector table and branch to
// the application's entry point.
__asm(" ldr r0, [r0, #4]\n"
" bx r0\n");
}
I will share my Bootloader and Application .CMD files
Bootloader.cmd file

Can you please help us check any configuration mistakes in .cmd file or any changes to be made for booting RTOS based code
from Non-RTOS bootloader
