Other Parts Discussed in Thread: DRA829
Hi expert,
Please tell me about OSPI boot of DRA829.
We are developing a board with reference to EVM and challenging OSPI boot.
However, I cannot load SBL even if I set boot mode to OSPI.
When connecting to the SoC using JTAG, the PC is stopped at 0x41800410.
If you check the signals of MCU_OSPI0_CLK and MCU_OSPI0_D1 (SPI Input), it will be as shown in the attached figure 1, and the signal of 9F (RDID) instruction will continue many times and will not proceed.
Could you give me some advice on this issue?
In addition, MX25UM51245G of MACRONIX is used for OSPI FLASH.
This device returns "C2803A" to the 9F (RDID) command, but when confirmed by CCS after OSPI boot, the value of "2FAC03A8" remains (Fig. 2).
However, when the RDID instruction was executed on the CCS after that, the correct value of "C2803A" could be read (Fig. 3).
Best regards
