Nice, that swaps odd and even around.

Lately, ChatGPT 5.1 has been less guilty of this and sometimes holds off answering fully and just asks me to clarify what I meant.

> As a side note: replacing the chip took longer than expected. I accidentally ordered a GD32F350R8T6, instead of the GD32F350RBT6 that was in the device originally. These two types differ in their flash sizes: 64 kB vs 128 kB. Don’t ask me why GigaDevice thought this naming scheme and this font was a good idea

An 8 looking almost exactly like a B. What a terrible idea.

Blame STM. Those clones copy (..among other things) the naming convention from STMicroelectronics parts like stm32f103c8t6/stm32f103cBt6. Guess what's the only difference between those.

Oh, and .. since STM likes binning/product segmentation, there's a good chance that if you ignore the reported flash size and still try to flash the full 128K, it works on those models..

Also the self patching back into protected mode! ugh - good thing they ordered more than one!

Doesn't the protection usually work such that it prevents reading the firmware but still allows you to erase and reflash it?

Assuming the other commenter is correct and the mcu is a clone of an ST product, then it's possible that the protection are fuses that destroy the pathways to the memory. They're one-time writable and cannot be undone. At my work that is how we protect our firmware with a similar ST product.

I'm not sure how it works in-silicon. Would be interesting to know how... but it's sunday afternoon

Very interesting. Is there any other simulation that also exhibits spontaneous illegal activity?

I did some searches when I posted this project, but I didn't find any at the time.

Thanks for this! I wasn't aware of this reference.

I had a great experience with using Hugo to set up a relatively complex multilang website with a lot of custom advanced workflows.

The twist is, OpenAI Codex did all the setup. I described precisely what I wanted in natural language. Codex did a perfect job.

A major milestone in the fight against wrongful medical determinations of SBS/AHT. Proud to have made a tiny contribution to this case (disclosure: signed an amicus curiae). More context: https://news.ycombinator.com/item?id=37650402

That doesn't seem totally implausible.

Have you tried OpenAI Codex with GPT5.1? I'm using it for similar GPU rendering stuff and it appears to do an excellent job.

Nothing, but looking at the current results either no one tried yet or it didn't work very well. And the pelican benchmark has been around for a while so the opportunity was there.
