You wouldn't download a printer. EPSON XP-442 custom SoC(realoid) emulated in QEMU running it's proprietary RTOS.

This was a really old project that I did (and abandoned) 3 years ago. Some day I should write about it. There are a lot of interesting things.

Just filed an EU DMA complaint against Alphabet for gatekeeping against secure Android derivatives like @grapheneos.org via Play Integrity. TL;DR: not certified ≠ not secure. Google lacks a FRAND certification process for non-OEMs that comply with objective security requirements.

NEW: The classic anime "Ghost in the Shell" turned 30 years old this week. Despite coming out at the dawn of the internet, it was incredibly prescient in terms of imaginig a future where governments use hackers for espionage, people use malware to spy on their loved ones, and much much more.

The phone industry release cycle is crazy. Like every year only the SoCs producer releases like 100 new, I cannot imagine how many phones models are released. with so many ones, that are also more complex and integrate and no technical info avalible, reusing or recycling them seems impossible.

I'm the only one worried about the ewaste we are gonna produce? I dunno I wish there were a lot less models and they all had an amazing community behind doing crazy hacks and mods, and when they are EOL, they or their parts can be reused.

Today, just by causality, I found that the devices reports the manufacturer to be "Shenzhen Lunci Technology Co., Ltd", that is the same as the microcontroller. And while it is obvious, I never looked at the manufacturer webpage (www.lenzetech.com), they clearly sold their MCU for this application.

the youtube vs yt-dlp arms race is hilarious, because of how lopsided it is. on the one hand, you've got a company with the GDP of Denmark who has about a manhattan-project's worth of developers they can assign to this. but on the other end, you've got every bored or annoyed javascript hacker.

Look I don't dislike LLMs but there is a little reflection I always do. Watching Fieren there was a conversation I really like where they said humans develop language to communicate, demons develop language to hunt For what purpose we are developing language on LLM? To please use? To convince us?

My motorbike (Zontes GK350) has an instrument panel that can do a bunch of things, including screen mirroring through an app (Carbit ride). How did they make it?

Why we should use tasks if we have a counters and switch cases? Really, see this shit. The different cases do different subtasks. What I have identified so far is one for the TPMS stuff, another for updating all the global attrs, one for the LCD and another for comm with the other MCU.

This is the Mainboard task btw, I forgot to mention it 😭

This is what I have done so far, I don't think there is nothing more interesting here as the rest of the magic happens on the other MCU and analyzing how all the data is passed is very painful. I'm very tempted to you know, replace some boot and assets images, but this thing cost +400€.

The software stack is an FreeRTOS plus + awtk (GUI) + FSC-Blueware (BT) + EC-SDK (screen mirror). The "architecture" is basically the awtk GUI obtains the all the information that it needs from a list of "global attributes" or communicating directly to the BT and EC sdk.

There are a lot of task running normally, most of them are from the different sdks and libs. Where all "the magic" happens is in the Mainboard task.

These last two components communicates to the MCU via SOFTWARE SPI. Crazy. Maybe they cannot use the main spi bus of the MCU because it was already used for the MMC?.

And of course for the BT and WIFI it uses the Feasycomm FSC-BW121 (it uses the RTL8821CS). Fun fact, I was unable to find the fcc id and the MAC address of both BTs (le and normal) and Wi-Fi are fake/not registered! (34:FA:4A C0:FA:4A 34:C6:4A).

So the main MCU is the Amt630hV100. There is little to nothing online about it. I found something on CSDN, but I was not able to download it. Besides the LCD, it seems that to this mcu is connected an MMC mem for the fw, an CMT2300A (for TPMS?) and another mcu that communicates to the rest of the 🏍️

The ref of this dashboard is 1164300-002000. It seems to be also used on the 350 T, R and X. The firmware is called AJ_B3-03, and internally it seems they called it "ZT350_IP_5". We are going to analyze the OTA firmware image I managed to obtain. How I obtained it is a story for another 🧵.
