Greetings and salutations!
I have a device that uses an N32G455RE. Unfortunately, its flash got corrupted. I have a dump of a working chip.
How can I program a specific region of the flash or the whole flash without touching the RAM, option registers, etc.?
I do not have a J-Link debugger and won't buy one, as I am not rich.
I have flashed a Nucleo board with an ST-Link to a J-Link just to find out that the ST-J-Link only supports ST chips.
What would be the cheapest and easiest option to program the Nations chip's flash without touching registers etc.?... -
Hi all,
I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
🔥 The Problem Started After Suspected ESD/PD Fault
I experienced a power issue or ESD event through a USB-C charger
After that, the NX20P5090 power switch was visibly burned and was replaced
Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
🧠 What I’ve Done So Far

Hello, I'm stuck in troubleshooting…
The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.
In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
When I press the flash button, it's detected by the system, flash icon appear on LDC display.... -
Is it possible to program npce388na1dx io chip by rt809f programmer ? Is there any way ?08-21-2024, 01:41 AM -
Hello I've had somebody bring in one of these charming little cameras to attempt retrieving data from the internal 32GB flash.
Something is damaged inside the cameras lens assembly I can hear it clunking around and it has probably dislodged the sensor, powering up the camera gives a blank screen and the focus motor sounds like it's having a fit.
The camera will not connect to a computer via USB in this state, I have no options no navigation, just power up and focus/zoom motor noises.
I think my best shot is to figure out a way to read the internal flash memory outside...
