i do not want to have to figure out why the network stack crashed on a windows embedded computer controlling a magnet thats currently sitting at 1T

please i swear to god i do not want to drive in for an emergency because windows update decided to fire on a system controlling a bunch of compressed gas that is rapidly heating

@azonenberg@ioc.exchange @gsuberland@chaos.social @whitequark@social.treehouse.systems well its build flow for the platform exists outside of CubeMX and is therefore at least moderately likely to actually work

@gsuberland@chaos.social @whitequark@social.treehouse.systems @azonenberg@ioc.exchange i remember uboot being very easy to bring up so you could just chainload your OS unless you need fast boot

@gsuberland@chaos.social @whitequark@social.treehouse.systems @azonenberg@ioc.exchange huh... do you get a freertos elf anywhere out of the build flow?

@gsuberland@chaos.social @whitequark@social.treehouse.systems @azonenberg@ioc.exchange do you have a screenshot of any bootflow config pages?

@gsuberland@chaos.social
@gsuberland@chaos.social @whitequark@social.treehouse.systems @azonenberg@ioc.exchange do you have optee enabled? I think it might be on by default, it was for the MP2 (its not actually necessary)

@gsuberland@chaos.social @whitequark@social.treehouse.systems @azonenberg@ioc.exchange https://wiki.st.com/stm32mpu/wiki/STM32MP1_boot_chain_overview
It took me an absurd amount of time to untangle what the intended bootflow is from these docs for the MP2

@gsuberland@chaos.social @whitequark@social.treehouse.systems @azonenberg@ioc.exchange the vendor tool for generating this is called fiptool
Replying to
@gsuberland@chaos.social
@gsuberland@chaos.social @whitequark@social.treehouse.systems for MP2 (although I think MP1 is very similar), the bootrom loads a binary from QSPI flash or EMMC.
(I think @azonenberg@ioc.exchange wrote something to stuff the appropriate headers from an elf file onto a raw binary)
From there the canonical bootflow is to load BL31 from that binary into SRAM which performs basic platform setup, loads the DRAM training blob into the ARC CPU and then jumps to the user code section

You may not like it but all your fancy semiconductors are made by machines controlled by computers that look like this
If you haven't been paying attention to ice you probably don't realize that the ice in my glass has recently undergone what I like to call a phase change
I expect that within the next 1-2 fiscal quarters it will have turned into a rapidly expanding ball of plasma
It's not my top priority, but the fact that there's an unclear number of members of Congress who are medically brain dead at any given time is probably something we should deal with at some point

@cliffle I believe in popular culture it comes from a correction to a 3 blue 1 brown video? Although my friend did publish this before that video iirc so it is an independent derivation

@cmb@cathode.church yeah the SY8301 looks small enough it probably comes out in a wash area wise

@cmb@cathode.church it's expensive, though possibly less so in quantity

@whitequark@social.treehouse.systems @regehr@mastodon.social in my experience as a TA (experimental physics) it's mostly the second; yes there are students who don't want to be there but there are also plenty who do. The problem is that troubleshooting is a skill you need to learn and practice, and that's something that they've had basically no exposure to until they get to their first intro lab.
In my department this is well understood to be basically the entire point of the intro lab and we very intentionally make the instructions less and less detailed as the year goes on
