Question
An OSPI Flash read error occurs when SBL xSPI is started, and the application cannot be read.
Please tell me how to resolve.
Status quo
When starting SBL xSPI, an error occurred in the application's RPRC format parsing, resulting in an error in reading.
RPRC is written to OSPI Flash, but a BOARD_FLASH_EFAIL error occurs in the Board_flashRead function.
Source code excerpt
<SDK Install Path>\pdk_j7200_08_04_00_19\packages\ti\board\src\flash\board_flash.c

if (NOR_read(flashInfo->flashHandle, offset, len, buf, readMode) \
!= NOR_PASS)
{
return (BOARD_FLASH_EFAIL);
