pca006132 eb28d7be3a firmware/rpc: fixed typo 2020-07-16 15:15:47 +08:00
pca006132 f78d673079 firmware/rpc: added `#[repr(C)]` for structs.
Previously the structs are in repr(Rust) which has no layout guarantee.

Robert Jördens e31ee1f0b3 firmware/i2c: rewrite I2C implementation
* Never drive SDL or SDA high. They are specified to be open
  collector/drain and pulled up by resistive pullups. Driving
  high fails miserably in a multi-master topology (e.g. with
  a USB I2C interface). It would only ever be implemented to
  speed up the bus actively but that's tricky and completely
  unnecessary here.
* Make the handover states between the I2C protocol phases (start, stop,
  restart, write, read) well defined. Add comments stressing those
  pre/postconditions.
* Add checks for SDA arbitration failures and stuck SCL.
* Remove wrong, misleading or redundant comments.

David Nadlinger 3f0cf6e683 runtime: Stop kernel CPU before restarting comms CPU on panic
Before, the system would enter a boot loop when a panic occurred
while the kernel CPU was active (and panic_reset == 1), as
kernel::start() for the startup kernel would panic.
