The load address varies by SoC. For AM335x, it’s often 0x402F0400 (just after the ROM-reserved area).
After the header comes the actual Thumb-2 or ARM code. This code is responsible for: dcboot.bin
When dcboot.bin fails, the board does . No serial output. No LED blinks. This is the hardest boot failure to debug. Common reasons: The load address varies by SoC
