Other Parts Discussed in Thread: HALCOGEN
I have been able to successfully port the Hercules_Ethernet_Bootloader example for LAUNCHXL2-RM57L in CCS version 10.4.0.00006.
My CCS project settings are:
- Connection - XDS110 USB Debug Probe
- Core - RM57L8xx
- Compiler version - TI v20.2.0 LTS
Note that I am using bare-metal HalCoGen drivers.
Using Debug mode, I am able to successfully compile and run tftp-based Ethernet bootloader on my development kit and able to transfer an application binary (basic led blinking code) using tftpd utility.
My bootloader code spans Sectors0-8 of Flash Bank0. So, I have fixed my application's start address beginning with Sector-9 in bl_config.h as follows :-
#define APP_STATUS_ADDRESS 0x00C0000
#define APP_START_ADDRESS 0x00C0020
The bootloader is able to receive the application code and run it. But, after I press the reset button, my application code is not able to load directly. I am trying to jump to my application from bootloader based on this check:
/* Check if update needed*/
uint32_t *FlagPtr;
FlagPtr = (uint32_t *)APP_STATUS_ADDRESS;
if( *FlagPtr == 0x5A5A5A5A )
{
UARTprintf("Starting LED Application ... \n\r");
g_ulTransferAddress = (uint32_t)APP_START_ADDRESS;
((void (*)(void))g_ulTransferAddress)();
}
