I need to look closer at this esp thing but y'all need to realize, undocumented op codes exist nearly on every chip.

This is a common thing. Intel does it, ST does it, everyone except fully open source chips. Which, doesn't necessarily mean riscv because an open source ISA can have closed sourced devices on the bus.

I'm not a fan of Blockstream Jade, but if you are shitting on it while using a device that needs closed source protection, you should look inward.

Your hardware wallet sucks, especially if it is running ads on bitcoin podcasts.

💯

as each chip manufacturer who licences/implements the esp32 riscV architecture is able to modify it to suit requirememts, all things are possible, and generally are.

undocumented op codes are common across mamy mcu and mpu.

not familar with the jade hardware, but my common hardware hacking go to is that most electronics hardware development is lazy and if they used a reference / dev hardware kit from a 3rd party and not the manufacturer then its going to be open to all sorts of shit.

ESP32 is so open with 3rd party hardware poorly implemented.

a good read of the manufactures documentation compared to dev docs usually turns up somethimg as a starting point.

love to see what you turn up.

What's wrong with the Foundation wallet?
