Hello,
Please let us know which board and SoC (GP or HS) you're testing with?
The binary built for GP and HS are not exchangeable.

Board: AM6442

I want to test with SOC ON HS .

follow the steps

R5
$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- am64x_hs_evm_r5_defconfig O=<output directory>/r5
$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- O=<output directory>/r5
$ cd ../k3-image-gen-<version>
$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- SOC=am64x HS=1 SBL=<output directory>/r5/spl/u-boot-spl.bin SYSFW_HS_PATH=<path to tisdk>/board-support/prebuilt-images/ti-sci-firmware-am64x-hs-enc.bin SYSFW_HS_INNER_CERT_PATH=<path to tisdk>/board-support/prebuilt-images/ti-sci-firmware-am64x-hs-cert.bin

Sign OPTEE and ATF binaries

$ $TI_SECURE_DEV_PKG/scripts/secure-binary-image.sh bl32.bin bl32.bin.signed

Hello,
One hypothesis is the SoC on your board is GP device instead of HS device:
==== How to know the device type (GP vs HS):
Onchip ROM dump Soc_ID of the device for all device types (GP and HS) from peripheral boot modes like UART, USB-DFU...

/* SOC ID definition */
typedef struct __attribute__((packed, aligned(4)))
{
    uint32_t            numBlocks;
    SOCID_PubInfo_t     pubInfo;
    SOCID_SecInfo_t     secInfo;
}
SOCID_Obj;

- On GP:
NumBlocks=1 (4 bytes)
sizeof(pubInfo)=32 bytes
Only the pubInfo is dumped by ROM code

- On HS:
NumBlocks=2 (4 bytes)
sizeof(pubInfo)=32 bytes
sizeof(secInfo)=168 bytes
Both the pubInfo and secInfo are dumped by ROM code

I'm attaching two sample log files captured from UART boot mode on GP and HS for your reference.

Best,

-Hong
