RE: https://infosec.exchange/@nieldk/116871917491185090 In case you missed it, look again . A fully standalone #blackmagicprobe (or, of course, you can use it with your PC, as usually) on #cardputer #m5stackhttps://codeberg.org/nieldk/blackmagic-cardputer Laptop-Free Standalone Operation: Acts as a completely self-contained field tool. You can scan, attach, read registers, hex-dump memory, and flash firmware directly using only the Cardputer's keyboard and screen—no PC required. Dynamic USB Mass Storage (⁠usbmode msc⁠): Overcomes the ESP32-S3's hardware USB limitations by letting you toggle the device into a USB flash drive. You can drag and drop ⁠.elf⁠ or ⁠.bin⁠ files directly from a PC into its internal 3MB storage, then swap back to debugger mode. Error-Proof Auto Pin Detection: The ⁠swd_scan⁠ command automatically tests both Grove pin orderings. If you accidentally swap your ⁠SWDIO⁠ and ⁠SWCLK⁠ wires when connecting to a target, the firmware automatically detects it and adjusts the logic. Built-In Target Emulator (⁠monitor emulate⁠): Spawns a synthetic STM32F103 target completely in the Cardputer's internal memory. It tricks the Black Magic stack into thinking a real chip is attached, allowing you to test flashing, GDB commands, and memory dumps on a plane or couch without any hardware wires. Smart Flash Protection & Auto-Detection: The on-device ⁠flash⁠ command reads file headers to automatically distinguish between ELF and raw binary formats. It will cleanly reject a file if the target address falls outside the connected chip's actual flash/RAM map, preventing accidental corruption. On-Device Command Console (REPL): Features a full interactive command line on the tiny screen that supports the Cardputer's full keyboard shift layers, allowing you to type native Black Magic monitor commands and symbols (⁠_⁠, ⁠!⁠, ⁠@⁠, ⁠#⁠) on the fly. 50-Line Scrollback Buffer: Includes a dedicated screen history layout navigated via keyboard shortcuts (⁠Fn + ;⁠ and ⁠Fn + .⁠), ensuring you don't lose track of long register dumps or multi-line error messages on the small display. Dual USB-CDC Mirrored Output: Simultaneously mirrors all on-screen command outputs to a secondary virtual COM port as raw text. You can plug it into a laptop terminal to easily log, view, or capture a full day of field debugging text.

You can now actually use it as a “standalone” blackmagic probe ;) Next up, include a “emulated” stm32, you know, when you don’t have a real device - wires around for testing

The build is based on litui’s work. With some fixes /confirmations/addons(cardputer) New features not in litui. On-device keyboard REPL so you can type BMP monitor commands directly on the Cardputer keyboard. 50-line scrollable history buffer with Fn+; and Fn+. navigation. Command output mirrored to USB CDC UART port simultaneously with on-screen display. GDB DTR debounce filtering Windows CDC enumeration transients that would suppress the keyboard REPL. Dirty-flag rendering so the display only redraws on keypress, eliminating flicker without needing double buffering. Startup logo splash screen. Cardputer-specific sdkconfig.defaults.cardputer with all display geometry, rotation, and SPI settings empirically confirmed on real hardware. Still not working, same as litui. JTAG, WiFi and networking, NV storage, CMSIS-DAP. Not yet tested on real hardware. Actual SWD target scan and attach (Grove wires in transit), RTT messages, semihosting.

Here is what that reality means for repository owners: No "Unbiased" Trial: The Presidium isn't an impartial court of law; it’s an elected committee designed to enforce the community’s specific anti-AI stance. In any gray-area decision, they will lean toward protecting human maintainers and platform infrastructure over giving "vibe-coded" projects the benefit of the doubt. The "Vibe Check" Problem: If an owner claims, "I wrote 60% of this and the AI only wrote 40%," but the repository looks, feels, and acts like unreviewed synthetic code, the board will almost certainly vote to remove it.

@esden@chaos.social I’ve got a small patch for the AT32F435/437 target (at32f43x.c) that decodes the EOPB0 SRAM/zero-wait split so the RAM map matches reconfigured parts. It’s based on an older revision, do you accept PRs against the older branch, or should I rebase onto current main?

Regarding #Codeberg and others decision on 100% ban on LLM. Leaving the decision on whether code is generated by LLM to a handful of people strongly against LLM usage carries a risk of non LLM contributing loosing their code, and reputation. On wrong assumptions. Example from my personal experience. My daughter got a low grade evaluation of her assignment in her 2nd grade term in college. She was accused of using ChatGpt . She did not, she is strongly against using LLM (environmental reasons). She complained, and got a higher grade, the teachers couldn’t prove she did wrong. Others, in her class, used ChatGPT, heavily, but was not discovered, they got higher grades. Codeberg decision will create same situations, a handful of people decide wrong or not. Repository owner will not be able to object (this was an option for my daughter). This is plain wrong, and personally I won’t keep my stuff there anymore.
