Hi,Experts,

      My  Custom Board  want to replace MT35XU512ABAG12  with  MT35XU256ABAG12. Can you tell me how to implenment .

      And I use  <uart_j721e_evm_flash_programmer_release.xer5f>   to download code into My Custom Board.

      Msg: 

      BOARD=j721e_evm；

      .

      I change the 《 \packages\ti\board\utils\uniflash\target\src\ospi\ospi.h》  line number 81, 

     < #define OSPI_FLASH_ID BOARD_FLASH_ID_MT35XU512ABA1G12 >   replace with   < #define OSPI_FLASH_ID BOARD_FLASH_ID_MT35XU256ABA1G12 >

      I use the make command is :

      ①、 cd \packages\ti\build\

      ②、make board_utils_uart_flash_programmer

.
