Recovering from Rock 4D brick

#1

My device did boot once with an SD card burned using default System image for MicroSD card [rk3576_bookworm_kde_512.img.xz], I could play with kde/hdmi/audio/ network … great! But trying to install image to eMMC I probably did something wrong with dd (crashing SPI perhaps) … No way to boot now, light stay green.
What can I do? Is there a way to reset device flashing from USB or TTY?

eMMC or ufs, the current version should only work with ufs, not eMMC.

#3

Radxa eMMC Module, model: VA001-16GB, suggested to buy together with Rock 4D by Arace Tech’s shop, is not supposed to work??
However even removing eMMC Module it is not booting anymore.
Please help…

Thank you for you help @Nasca.
I did follow this guide for “Installing System to MicroSD Card” but can’t boot anymore… I’d love to follow “Flashing SPI Boot Firmware” but the only way documented is to boot an SD card and use RSETUP so I’m stuck :frowning:
Could you please provide instructions for flashing SPI Boot Firmware another way?
Thanks.

  1. copy /lib/u-boot/rock-4d on the sd card to your PC
  2. make ROCK 4D enter the Maskrom mode
  3. cd rock-4d ,excute the cmd to update the spi : sudo bash setup.sh maskrom_update_spinor

Way to enter Maskrom for ROCK 4D:

  • Press and hold the Maskrom button
  • Then power up the board
  • Use rkdeveloptool to verify that the board has entered Maskrom mode.

Did try and it fails:

sudo rkdeveloptool ld
DevNo=1 Vid=0x2207,Pid=0x350e,LocationID=302 Maskrom

sudo bash setup.sh maskrom_update_spinor

It seems your spi flash is broken, can the spi flash be recognized when booting from the sd card?

#11

Thanks again @Nasca but I can’t boot from the sd card since it doesn’t … light stay green :sleepy:.
Also tried from another PC running Windows. RkDevTool is detecting a maskrom device but no advanced functions works (ReadFlashID, ReadFlashInfo, ReadChipInfo, … fails).
Another idea?

To add also: It is permanently in maskrom mode, no need to push button when powering up, whether I plug a bootable SD Card or not. Referring to documentation could be because SPI is not there…
