VA416xx Bootloader Application
=======
This is the Rust version of the bootloader supplied by Vorago.
## Memory Map
The bootloader uses the following memory map:
| Address | Notes | Size |
| ------ | ---- | ---- |
| 0x0 | Bootloader start | code up to 0x3FFC bytes |
| 0x3FFC | Bootloader CRC | word |
| 0x4000 | App image A start | code up to 0x1DFFC (~120K) bytes |
| 0x21FFC | App image A CRC check length | word |
| 0x21FFE | App image A CRC check value | word |
| 0x22000 | App image B start | code up to 0x1DFFC (~120K) bytes |
| 0x3FFFC | App image B CRC check length | word |
| 0x3FFFE | App image B CRC check value | word |
| 0x40000 | End of NVM | end |
## Additional Information
As opposed to the Vorago example code, this bootloader assumes a 40 MHz external clock
but does not scale that clock up. It also uses a word (4 bytes) instead of a half-word for the CRC
and uses the ISO 3309 CRC32 standard checksum.
This bootloader does not provide tools to flash the NVM memories by itself. Instead, you can use
the [flashloader](https://egit.irs.uni-stuttgart.de/rust/va416xx-rs/src/branch/main/flashloader)
application to perform this task using a CCSDS interface via a UART.
The bootloader performs the following steps:
1. The application will calculate the checksum of itself if the bootloader CRC is blank (all zeroes
or all ones). If the CRC is not blank and the checksum check fails, it will immediately boot
application image A. Otherwise, it proceeds to the next step.
2. Check the checksum of App A. If that checksum is valid, it will boot App A. If not, it will
proceed to the next step.
3. Check the checksum of App B. If that checksum is valid, it will boot App B. If not, it will
boot App A as the fallback image.
You could adapt and combine this bootloader with a non-volatile memory to select a prefered app
image, which would be a first step towards an updatable flight software.
Please note that you *MUST* compile the application at slot A and slot B with an appropriate
`memory.x` file where the base address of the `FLASH` was adapted according to the base address
shown in the memory map above. The memory files to do this were provided in the `scripts` folder.

VA416xx Flashloader Application
========
This flashloader shows a minimal example for a self-updatable Rust software which exposes
a simple PUS (CCSDS) interface to update the software. It also provides a Python application
called the `image-loader.py` which can be used to upload compiled images to the flashloader
application to write them to the NVM.
The software can quickly be adapted to interface with a real primary on-board software instead of
the Python script provided here to upload images because it uses a low-level CCSDS based packet
interface.
## Using the Python image loader
It is recommended to run the script in a dedicated virtual environment. For example, on UNIX
systems you can use `python3 -m venv venv` and then `source venv/bin/activate` to create
and activate a virtual environment.
After that, you can use
```sh
pip install -r requirements.txt
```
to install all required dependencies.
After that, it is recommended to use `./image-load.py -h` to get an overview of some options.
The flash loader uses the UART0 interface of the VA416xx board to perform CCSDS based
communication. The Python image loader application will search for a file named `loader.toml` and
use the `serial_port` key to determine the serial port to use for serial communication.
### Examples
You can use
```sh
./image-loader.py -p
```
to send a ping an verify the connection.
You can use
```sh
cd flashloader/slot-a-blinky
cargo build --release
cd ../..
./image-loader.py -t a ./slot-a-blinky/target/thumbv7em-none-eabihf/release/slot-a-blinky
```
to build the slot A sample application and upload it to a running flash loader application
to write it to slot A.
You can use
```sh
./image-loader.py -c -t a
```
to corrupt the image A and test that it switches to image B after a failed CRC check instead.

# [v0.2.0] 2024-09-18
- Documentation improvements
- Improved UART typing support: Validity of passed pins is now checked properly
@ -17,12 +17,17 @@ and this project adheres to [Semantic Versioning](http://semver.org/).
- Added `va41620`, `va41630`, `va41628` and `va41629` device features. A device now has to be
selected for HAL compilation to work properly
- Adaptions for the UART IRQ feature which are now only implemented for the RX part of the UART.
## Fixed
- Small fixes and improvements for ADC drivers
- Fixes for the SPI implementation where the clock divider values were not calculated
correctly
- Fixes for UART IRQ handler implementation
- Add new IRQ router initialization method `irq_router::enable_and_init_irq_router`. This method
also sets the initial values of some registers to 0 where the datasheet and the actual reset
value are inconsistent, which can lead to weird bugs like IRQs not being triggered properly.
