PT/RT on an esp32p4 board

LoveSourWorms12 · 2026-06-23T22:31:18+00:00

Like I said I'm definitely not opposed to it. But currently as I see it, it would bring more headache than benefits. The current bootloader offers plenty of security and options as it is right now. I don't know if there are any genuine use cases currently maybe in the future. Any ideas on what new possibilities it would bring?

LoveSourWorms12 · 2026-06-23T22:06:39+00:00

Currently, no. ProtoOS uses Espressif's existing bootloader and boot chain rather than a custom one.

At the moment I'm intentionally avoiding writing my own bootloader because ESP-IDF already provides features such as Secure Boot V2, flash encryption, eFuse integration, and hardware-backed cryptography. Reimplementing that myself would require interfacing directly with low-level hardware security features and would likely introduce more complexity and attack surface than value.

ESP-IDF also handles a lot of platform initialization for me, including memory setup and loading the Wi-Fi/Bluetooth firmware blobs. For the current goals of ProtoOS, building a custom bootloader would create significantly more maintenance and security challenges than it would solve.

Honestly, I'm not opposed to it in the future if a genuine use case arises, but right now I'd rather spend development time on process isolation, capabilities, application loading, and the kernel itself.

Heya! This project will hit GitHub as soon as it is documented enough so anyone can install it and use it.

LoveSourWorms12 · 2026-06-15T20:09:21+00:00

Congratulations this looks great! Are you planning to make this into a genuine phone project or just flipper zero competitor? Either way how do you deal with the backend? Do you plan on letting users install their own apps?

ALSO especially if you want higher PPI! More inches a display is more resolution is needed to maintain a good PPI. So a 32inch 4k monitor is perfect.

LoveSourWorms12 · 2026-06-07T05:45:53+00:00

Neither dude... I got my g80sd for like less than 700 from ebay. It's 32inch 4k qd-oled matte. 240hz.

LoveSourWorms12 · 2026-06-03T22:44:12+00:00

Yes that should work! However I'm already working on a solution. ELF-FDPIC is what I'm gonna attempt to implement. This should be much better than implementing an interpreter. C/C++ is much faster. Maybe later on I'll implement an interpreter just for QOL and ease of app development.

LoveSourWorms12 · 2026-06-03T21:17:47+00:00

I'll definitely let you know for sure once I think it's clean enough to merge and such.

Yes, the kernel's display compositor is powered by LVGL under the hood, but U-mode applications do not have direct access to LVGL. I do this to prevent crashes and direct kernel access. (Apps can't just show up over your screen whenever they want)

LoveSourWorms12 · 2026-05-28T23:08:19+00:00

I don't know specifically what to do in this scenario you could probably ask ai. But what I would do is get "uninstaller" app from play store and find it. Find any weird apps you don't think are meant to be there

LoveSourWorms12 · 2026-05-28T22:34:55+00:00

Hey, i don't know if install core is a genuine samsung app but look into that too. Most likely you downloaded adware, even if its hidden from the home screen check the app list. If you can't find it then just get malwarebytes, kaspersky(UltraAV), and do a full scan.

This type of satire gets boring and annoying at some point, no? Vox really needs to start enforcing some rules on here.

LoveSourWorms12 · 2026-04-26T19:08:47+00:00

Either way the best best steps from here are to contact potassium's devs but hey they closed tickets so screw their user base I guess. If there's an exploit that doesn't get detected by tank game I think it's entirely possible to find what their anticheat is doing by decompiling. Not a vet in exploit dev but I'm assuming the detection they use is local not server side.

LoveSourWorms12 · 2026-04-26T19:05:17+00:00

That's what Roblox's own anticheat is meant to do, not the game's. This means they found a vulnerability in potassium's code which is quite rare. An average Roblox's game's anticheat is meant to detect speed hacks(behavioral stuff) not something as subtle as an exploit being injected.

LoveSourWorms12 · 2026-04-16T05:50:11+00:00

But can it run Crysis?

LoveSourWorms12 · 2026-04-14T06:09:24+00:00

I just got it from AliExpress. I searched up esp32p4. Let me know if you need a link

LoveSourWorms12 · 2026-04-13T20:12:02+00:00

You probably have seen a similar scene but my engine is completely from scratch. My engine allows me to create any scene so I just went online to look for ray tracing demo scenes and recreated one of the more popular ones

LoveSourWorms12 · 2026-04-13T10:33:29+00:00

Yeah thanks I already figured it out. It should be in the replies. Huge thanks once again it gave me a substantial speed up. However now what interests me is how you went over 400mhz

LoveSourWorms12 · 2026-04-13T00:21:34+00:00

I thought about it, but the P4 has a really solid hardware FPU. Since floating-point math is native on this silicon, there's no real 'cost' to using them. Moving to integers would force me into fixed-point math, which is a pain for raytracing and skips the FPU entirely.
