tiny4412/super4412 sdk 1506 boot from sd card

hi,

i have tiny4412/super4412 sdk1506 and can not boot from sd card!

i test my sd card  on tiny4412 sdk1312 and its boot from sd card without
problem!

what's wrong on  tiny4412/super4412 sdk1506 ???

I Solved my problem.....

tiny4412sdk1312 and tiny4412/super4412sdk1506 use different superboot.bin.

For each of them use its superboot in two level :

1- in SD-Flasher .....
2- in images folder in SD card...

i attach these two superboots...

thanks FRIENDLYARM
