[SOLVED] stuck at emmc - dr_dre - 04-28-2018
Hello all,
ill try tell my problem.
I used u-boot-flash-spi-rock64.img.xz on microsd to flash spi and be able to boot from emmc.
I used android tv as my emc image.
I played with it for some time ( worked okish btw)
ANd now im lost.
I cant find my emmc ( I lost it) ( yeah blame me
)how will i be able to boot from micro sd .
As soon as i turn on power all 3 leds all are lit bright and are not doing anything. neither will he boot from usb or from microsd. ( tried several sd cards and boot imgs)
Any help is appreciated.
Cheers.

follow this link to erase your SPI Flash: http://wiki.pine64.org/index.php/NOOB#Erasing_and_Rewriting_SPI

But as I said booting from sd isnt possible anymore.
Any other ideas besides creating a ticket at Pine-support ?

There is pins you can short to disable SPI Flash, according to Lukasz it's the last two pins at the bottom row

(Yes, I'm stalking you, you rascally wabbit!)
Yup, it's the two pin header near the white/red leds and pwr/reset buttons, marked "eMMC en/dis"(able)... you short the two pins to disable the eMMC... or just unplug the eMMC from the board (all the jumper does is stop the eMMC clock by pulling to GND).
What I'm not clear on is why you needed to flash the SPI in order boot from eMMC... as the rock64 boot sequence is SPI -> eMMC -> SD, so if there was nothing on the SPI (i.e. as shipped from factory), it will then try the eMMC (if installed, and the disable pins not jumpered), and then the SD card...

Ok what should be normal behavior from rock64 board after i flashed spi with u-boot-flash-spi-rock64.img and i dont have emmc anymore. Problem is i get 3 bright leds immediately after power on. no life can be seen ( no ethernet leds no nothing.) The shorten of the spi flash did not help either. My next move would be to get serial working to see any kind of messages.
or am i moving in the wrong direction.

RE: stuck at emmc - dr_dre - 04-29-2018
is there any way to write spi to factory settings again ( using uart or so) this is the output from serial

Hello, nice that it works. Can you tell me which adapter you have used to read the rock serially?
RE: stuck at emmc - dr_dre - 04-29-2018
yes i used a FTDI232 to do the job .
