In switch oled, where goes dat0 pin from emmc? To where?

[xiran64]

Hi to all!!!

I have a doubt, where goes dat0 pin from emmc? To cpu directly?

Thx for your answer jkyoho!

It goes to the mystery chip GCBRG HAC STD, it´s a Dat0 alt point for OLED version, but i can´t see if it goes to cpu, or to another location.

There is an alternative location of data0 near the shield but you need drill into pcb (5 layers).

Oh, thx whisky9!
I have made various things to try to revive My oled, change emmc (i have damaged the original), rebuild nand, without luck, it can use hekate, but when i try to boot, stay in nintendo logo, and then, black screen... no second state... hekate can grab info for max, and various ic, so i don't know, what more can i do... i put an emmc from an old celular (new arrives in 2 weeks), i've write boot0/1 with octoplus, and i've Made a nand restore to have correct cal0, and correct read from tegra Explorer with my prod.keys, i've use nand manager, but it can't see system more than 16.0.2, i put 16.0.3 or 16.1.0, but nand manager can't read the versión number, i've upgrade a switch Lite, to 16.0.3, and again, it can't read version number nand manager, but it works fine

I've found this damage, and put a resistor of 10k to the right and a cap of 1uf to the left

The cap is 100nF.

I´ve take reads in the coils, and have this voltages:

After one month and half, the oled revives!
It's working with an emmc from a cell phone.
