I purchased a Nanopi R2C Plus (8gb onboard eMMC) and I a noob at debugging via UART serial, can someone give me some pointers on what to do? I think I overwrote my eMMC storage and now my board does not boot.

### ERROR ### Please RESET the board ###
There is little information in the WIKI, I haven't found what "RESET the board" means? also there is a method to try to force the bootloader to once again try to boot from MicroSD card " Method 2 : Insert the TF card, short-circuit the Maskrom contacts and then power on (need to keep the short-circuit for about 3 seconds), it will start from the TF card"
I am not sure I see where the "Maskrom contacts" are that I need to short circuit, its not in the diagrams on their site. Could it be this?
Some progress by short circuiting those:

The "RESET the board" message is just because the SPL hit some fatal error and was unable to continue booting. It seems like you're hitting some kind of MMC initialization error. I'm not familiar with this device so not sure if MMC1 is what is supposed to be trying to boot from or not..

I have the same issue. I do not have a console yet, ordered one the supports 1.5mbps to be able to see something, the one I have only supports 0.96mbps. Is your SYS led red and lit? not blinking ?
I have no solution yet!
