@maxi is teasing with itelma M74.9 which uses at32f435zmt7+L9779?! Well at least that at32f435zmt7 has an English datasheet.

https://caxapa.ru/1203080.html says that at least two vcc/vss pins are flipped

Which sometimes uses Geehy apm32F407VGT7

Which just takes rusEFI firmware and blinks LEDs and connects via USB, as is. Software jump to DFU turns off activity but does not produce USB DFU device.

spi SD and MSD works on Geehy.

Mostly fun but could end up being part of a silly evil plan :)

S32K update: not really available yet.
Time flies, they now have S32K3 - automotive, lock step, ARM, GCC

Exactly one huge S32K344-wb eval board is available for order today but mouser promises a few more later this month :)

Exactly one smaller MR-CANHUBK344 again mouser promises more soon.

hi forumers!
Wanted to know if there are people still working on the 5V automotive graded MCU's?
People are definitely not making progress on Kinetis and Cypress.

It still builds so firmware is up to date but there are maybe two Kinetis units in existence and maybe zero or one Cypress on this planet.
we started to draw a basic board, useful for a simple setup at m73 engine ... using a 120pin fujitsu-spansion-cypress-infineon chip ... a strange son with many mothers .... a S6E2H44 with 256Kb of flash mem

so we are thinking to put a minimal firmware into this device in order to create a limited but simpler ecu

if you have a port for a Fujitsu/Cypress mcu we can try to build for this device

i do not know the flash mem needed for ruefi project but maybe we can reduce while compiling/porting

what about risc-v family? e.g. https://habr.com/ru/articles/777504/
it has plenty of fancy features that might fit perfectly the engine management requirements.
