How to eraese defekt SPI ?

[linuxfreund]

Hi there,
unfortunately I've filled the SPI with garbage while updating to new U-Boot.
U-Boot SPL 2024.04-rc2 (Feb 14 2024 - 00:00:00 +0000)
Trying to boot from SPI
Trying to boot from MMC1
Card did not respond to voltage select! : -110
spl: mmc init failed with error: -95
Trying to boot from SPI
Trying to boot from MMC2
Card did not respond to voltage select! : -110
spl: mmc init failed with error: -95
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

Question: how to reset the bord and flash a correct version of U-Boot? Pressing the "Reset" button didn't help.

Thanks
Andreas

Per the docs on pine64.org:

"Even if you need to recover from a defective bootloader written to the SPI flash, you can simply short pin 6 of the SPI flash to GND and boot. This will render the SoC bootrom unable to read from the SPI flash and have it fall back to reading the bootloader from other boot media like the eMMC or Micro SD card."

Thanks, I found the docu and get it in Masked Mode. But where can I find the file SPI_new.bin ?

Good nwes: i can now boot the system again
Bad news: I think entering the Maskrom mode again isn't possible, because one connection from the SPI chip was broken while removing the clamp.

There's no specific "SPI_New.bin, but most use TowBoot since it's the easiest to flash to the SPI, with their installer image that you can boot from an SD

Thanks, but with Towboot there is the same problem with "sf probe". So I think the SPI is broken. I had to leave SD Card with U-Boot while poweron the Laptop, no problem.

Or it's possible to flash the SPI on the EMMC ? That's my boot device for Fedora, while /home is on NVME.

Thanks

If you are able to boot from an SD card, you can flash your preferred OS/bootloader to eMMC by `dd`ing to `/dev/mmcblkX`. Use `lsblk` to figure out what `X` should be.

If you need Tow-Boot you can also download an installer image, but you want the one for "shared storage" and not "dedicated storage." ("Dedicated storage" is for your now-dead SPI chip.)
