AM2634: How to Load the Program Directly into the Flash Memory

Part Number: AM2634
Other Parts Discussed in Thread: UNIFLASH, SYSCONFIG

Tool/software:

Hi teams,

I am Working on AM2634-cc and i have a doubt what ever we are Flashing in CCS the Program is not Storing into the flash memory and it will Store on the RAM memory, I need to Load the program directly into the FLASH memory not in RAM.

so i did Flashing by Uniflash and UART Bootloader so it is working fine,

But my requirement is i need to FLASH the Program Directly into the Flash not in RAM memory, so i did small changes in the Sysconfig.

I want the Clear information what are all the Things i need to change in the Sysconfig?

I have modified section memory address

Initially sections were pointing to OCRAM but I have changed to Flash. But, I got the ERROR

Cortex_R5_0: Error Code 30000001
Cortex_R5_0: Run failed...
Cortex_R5_0: File Loader: Failed to terminate flash programming: The algorithm failed to flash the data. Power cycle the EVM and try again.
Cortex_R5_0: GEL: File: D:\TI_workSpace\gpio_led_blink_am263x-cc_r5fss0-0_nortos_ti-arm-clang\Release\gpio_led_blink_am263x-cc_r5fss0-0_nortos_ti-arm-clang.out: Load failed.

Any solution for this?

Appreciate your support on this!

What is the boot mode you are using?

Hi Nilabh Anand,

QSPI BOOT MODE

I am Using This mode

Hi Aakash,

Few clarifications:

1. In order to flash a image on to flash please refer to the set of tools provided here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/TOOLS_FLASH.html

QSPI BOOT MODE

This is not correct, you will need to write the image first on the flash then put the boot mode as QSPI, as in QSPI boot ROM expects the SBL and application image to be present in Flash.

Hi Nilabh Anand,

Thank you for replay now i understand few ways to flash our code into the Flash,

I have the one doubt, If we flash our code from the CCS IDE our program is stored in the RAM memory, So, my requirement is, i need to flash our code from the CCS IDE and i need to store the program into the FLASH by using the CCS IDE.

so for this any thing did i need to change in sysconfig?

Sharing again for your reference: You can use SBL JTAG for flashing the program on to flash from CCS: software-dl.ti.com/.../EXAMPLES_DRIVERS_SBL_JTAG_UNIFLASH.html

Please also note that AM263x device is an external flash device, if you are trying to compare it with an einternal flash device where you can load program to flash, the experience would be different in two scenarios.
