Ok, for me it is not important to flash emmc. I can use system from card. And I want use this method. So, what should I do step by step? For this momet I have got old version on the emmc and ne we on sd card. If i remove card, BBB boot from emmc. If I insert card, BBB boot from sd card. But when I am using system form card there is problem with this PWM by adafruit in python. When I use this comand: sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100 after rebooting BBB dont get up. All leds are off. With card, without don't matter. BBB is off.
