fail during Mfgtool download

sethhorus — Tue, 24 May 2022 12:26:23 GMT

Hi,

I design a imx6q circuit board.

I try firmware download by mfgtool,but stop "Jumping to OS Image".I can see uboot information and board stop "starting kernel......" in serial console.

I use "DDR test tool V3" to stress test.

Pass DDR Stress test.

I really don't know whats wrong and need help.

THE DDR STRESS TEST IS FINE

enter desired START freq (135 to 672 MHz), then hit enter.
Note: DDR3 minimum is ~333MHz, do not recommend to go too much below this.
528
The freq you entered was: 528

Enter desired END freq (135 to 672 MHz), then hit enter.
Make sure this is equal to or greater than start freq
528
The freq you entered was: 528

the board stop "starting kernel......" in serial console during download by mfgtool.

Boot from USB for mfgtools
Use default environment for mfgtools
Run bootcmd_mfg: run mfgtool_args;bootz ${loadaddr} ${initrd_addr} ${fdt_addr};
Hit any key to stop autoboot: 0
=> run bootcmd_mfg

I burn other boards(different circuits and same DDR,PM）with same mfgtools.they are fine
