Should check your hardware configuration first
do you have DRAM settings parameters? (ref. https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/iMX-8M-Mini-Register-Programming-Aid-DRAM-PLL-setting/ta-p/1112094)
and what's boot device for your board? (https://community.nxp.com/t5/i-MX-Processors/BOOT-mode-iMX8MM/m-p/1211393#M167718)
DRAM need initial parameters and firmware of memory controller
my steps only for LPDDR4 and setting boot mode for SD/MMC devices
if you use another configuration need to modify some steps
or you just missed 'sync'
sudo dd if=./iMX8M/flash.bin of=/dev/mmcblk0 bs=1024 seek=33 conv=fsync
