This was triggered by moving log_init and adding i2c_init on top of
the existing ethernet setup/init after the timer setup and enable.
Thanks @cjbe for debugging.
Also move the RCC peripheral enable calls out of i2c and eth setup.
close#55
supersedes #62
The CPU is allowed to access normal memory writes out-of-order. Here
the write to the OWN flag in the DMA descriptor (normal memory) was
placed after the DMA tail pointer advance (in device memory, so not
reorderable). This meant the ethernet DMA engine stalled as it saw
a descriptor it did not own, and only restarted and sent the packet
when the next packet was released.
This fix will work as long as the CPU data cache is disabled. If we
want to enable the cache, the simplest method would be to mark SRAM3
as uncacheable via the MPU.
Previously, if a message spanned the end of the
receive ring buffer, the last byte in the buffer
would be missing from the to-be-decoded message,
leading to a parse error or panic.
With this commit, >3M commands were exchanged
over one socket without further issues.
28: Read MAC address from EEPROM r=jordens a=cjbe
Try and read the unique MAC address from EEPROM.
If the EEPROM can not be read (e.g. on the unpatched hardware version 1.0 where the EEPROM is unpowered) a hardcoded default of 10:E2:D5:00:03:00 is used.
The MAC address found / used is logged. At the moment the only way of accessing this log is via semihosting.
Closes#23
30: build(deps): bump serde from 1.0.99 to 1.0.100 r=jordens a=dependabot-preview[bot]
Bumps [serde](https://github.com/serde-rs/serde) from 1.0.99 to 1.0.100.
<details>
<summary>Release notes</summary>
*Sourced from [serde's releases](https://github.com/serde-rs/serde/releases).*
> ## v1.0.100
> - Provide `serde::ser::StdError` and `serde:🇩🇪:StdError` which are either a re-export of `std::error::Error` (if Serde's "std" feature is enabled) or a new identical trait (otherwise).
>
> ```rust
> #[cfg(feature = "std")]
> pub use std::error::Error as StdError;
>
> #[cfg(not(feature = "std"))]
> pub trait StdError: Debug + Display {
> fn source(&self) -> Option<&(StdError + 'static)> { None }
> }
> ```
>
> Serde's error traits `serde::ser::Error` and `serde:🇩🇪:Error` require `std::error::Error` as a supertrait, but only when Serde is built with "std" enabled. Data formats that don't care about no\_std support should generally provide their error types with a `std::error::Error` impl directly:
>
> ```rust
> #[derive(Debug)]
> struct MySerError {...}
>
> impl serde::ser::Error for MySerError {...}
>
> impl std::fmt::Display for MySerError {...}
>
> // We don't support no_std!
> impl std::error::Error for MySerError {}
> ```
>
> Data formats that *do* support no\_std may either have a "std" feature of their own as has been required in the past:
>
> ```toml
> [features]
> std = ["serde/std"]
> ```
>
> ```rust
> #[cfg(feature = "std")]
> impl std::error::Error for MySerError {}
> ```
>
> ... or else now may provide the std Error impl unconditionally via Serde's re-export:
>
> ```rust
> impl serde::ser::StdError for MySerError {}
> ```
