Part Number: AM6412
Hi expert,
sdk :ti-processor-sdk-linux-am64xx-evm-09.00.00.03
custom board
We are testing custom board based on AM6412 SOC.When i booting custom board via uart , it prints "Loading Environment from MMC... MMC: block number 0x3500 exceeds max(0x2000)", the same print appears when I flash the u-boot.img file into emmc, print log as follows:

My custom board EMMC chip info is as follows:

I noticed that my custom board, emmc boot partition capacity is only 4M, I don't know if the error printing above is caused by this.
How to flash tiboot3.bin ,tispl and u-boot.img binaries to emmc, I need your help.
Best regards
