Rock Pi E v3.0 - Corrupted emmc, cannot boot

[grbg]

Hello,

I got my Rock Pi E, I was toying around from the SD card successfully, and then decided to install it onto the onboard emmc.

From here onwards, no boot whatsoever. I cannot boot from the SD card either. I tried reflashing on the SD the image that I used from the getgo (armbian) without success, the radxa debian image didn’t boot either.

I think the boot order is emmc => sd => USB (which I find debatable given the fact that emmc are now soldered (weird choice by the way, most radxa board come with soldered emmc now, so cannot flash the module externally…). But shouldn’t the card tried SD boot when the emmc does not boot?

I wanted to try and short the emmc to force sd boot without success, I cannot get to maskrom mode.
I wonder if I need to solder the “buttons” for recovery/reset underneath the board (no physical button wtf?).

What are my options to recover and boot from SD again?

Regards

To enter Maskrom mode, you usually need to short the recovery button. Please refer to the following:

ROCK Pi E V3.00 (embedded emmc)- Maskrom Mode via USB Male A to Dupont Cable

Hi @Sangam_Prajapati First, make sure you have correctly connected the USB Male A to Dupont Cable to the board’s pin 14, pin 16, and pin 18. If the connection is correct, press and hold the recovery button on the board (located on the bottom side beneath the Ethernet port) before powering on the board. Once powered on, your computer should recognize a Maskrom device. Depending on your operating system, refer to the following documentation to choose the appropriate flashing method: https://do…

I am waiting for my dupont to USB cables, I have the UART ones which surprisingly does not give me anything at all, no output. Even when (supposedly) in maskrom, which I can’t confirm that the shorting I’m doing works.
I’ll report when I get the cables whether I successfully get into maskrom or not.
