LP-AM243: Can the Flash on the board be erased? format?

Hi Shaoxing,

Documentation of flashing tools can be found here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_02_00_12/exports/docs/api_guide_am243x/TOOLS_FLASH.html

This describes how to get UART Uniflash tool help: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_02_00_12/exports/docs/api_guide_am243x/TOOLS_FLASH.html#autotoc_md816

Default cfg files for understanding the tool syntax are located in <SDK>\tools\boot\sbl_prebuilt\am243x-lp.

I'm not sure what you mean by "initialize", but these docs cover programming the flash.

The flash can be erased using the UART Uniflash "erase" command:

• First, load SBL UART Uniflash to the LP: python uart_uniflash.py -p COM<x> --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg
• Next, erase part of the flash from 0x0 to 0x7FFFF: python uart_uniflash.py --operation=erase --flash-offset=0x0 --erase-size=0x80000 -p COM<x>.

For the LP, COM<x> is the XDS110 Class Application/User UART, see https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_02_00_12/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html#CCS_UART_TERMINAL
