Hi, Experts.
Boot Mode is currently set on my custom board as follows.

1 means 3.3v and 2kOhm connected, and 0 means GND and 2kOhm connected.
TMDS243EVM is designed to operate normally in QSPI mode when BOOTMODE5,6 is pulled up and UART mode when BOOTMODE5,6 is pulled down,
so my custom board can be set up like this.
However, BOOTMODE5,6 is all turned on in UART boot mode regardless of pull up/down.
sbl_null was downloaded normally. Is it uart booting as backup boot mode because the bootloader is not running normally?
(Additional Information)
The download was completed successfully, but it appears to be entering backup boot mode. (This was discovered while reworking the soldering.)
What should I do?
Currently, SPI flash has W25Q128JV (winbond) attached.
Win11, CCS12.7.1, SDK11.01.00.17
