-# USB Files Source Documentation
-
-## Source
-
-We sourced the USB files in Marlin from the Atmel ASF (Advanced Software Framework). The framework provides a variety of examples which were utilized in this project.
-
-Atmel doesn't provide these files in a source repository but they can be extracted from ASF, which can be downloaded from Atmel.
-
-[Advanced Software Framework](https://www.microchip.com/en-us/tools-resources/develop/libraries/advanced-software-framework)
-
-## Modifications
-
-The files are mostly unmodified except for minor cosmetic changes but some more significant changes were needed.
-
-The changes that prompted the addition of this README file are listed below. Other changes may have been made prior to this.
-
-1. Modified `uotghs_device_due.c` to resolve race conditions that could leave interrupts asserted when freezing the peripheral clock, resulting in hangs and watchdog resets due to the ensuing interrupt storm.
-
-## Version Information
-
-We don't know the exact version of ASF used as the source. However, the copyright information in the files indicates they are from 2015.
-
-## Upgrade Considerations
-
-We looked at the ASF 3.52.0 files released in 2022 but saw no immediate benefits to justify an upgrade. It's important to note that the files in Marlin don't follow the same folder structure as the files in ASF, which complicates the process of comparing and applying updated files.
-
-When these files are updated it's important to carefully compare them to Marlin's versions so any improvements in the Marlin sources are brought forward.
-
-It would be best to make Marlin's directory structure align with ASF or at least document the source of each file to ease future updates.

-# HC32F460 HAL
-
-This document provides notes on the HAL for the HC32F460 MCU.
-
-## Adding support for a new board
-
-The HC32F460 HAL is designed to be generic enough for any HC32F460-based board. Adding support for a new HC32F460-based board will require the following steps:
-
-1. Follow [the usual instructions](https://marlinfw.org/docs/development/boards.html#adding-a-new-board) to add a new board to Marlin. (i.e., Add a pins file, edit `boards.h` and `pins.h`, etc.)
-2. Determine the flash size your board uses:
-   - Examine the board's main processor. (Refer the naming key in `hc32.ini`.)
-   - Extend the `HC32F460C_common` base env for 256K, or `HC32F460E_common` for 512K.
-3. Determine your board's application start address (see [below](#finding-the-application-start-address))
-4. Set `board_build.ld_args.flash_start` to the app start address once you've found it. If your board doesn't use a bootloader, you may be able to use the "ICSP" header or DFU. This document will be updated once we have more information about flashing without a bootloader.
-
-### Finding the application start address
-
-If the board contains a bootloader you'll need to find the application address. This is the address the bootloader jumps to after it's done. You can find this address in a few different ways:
-
-#### 1. Using log messages
-
-If you're lucky, the bootloader may print the app start address on the serial output during boot. To check for this, use your favorite serial monitor to observe the serial output when you power on the board. Look for a message like "Jumping to 0xC000" or "GotoApp->addr=0xC000". This line would be printed before Marlin's "start" message.
-
-Example:
-
-```
-[...]
-version 1.2
-sdio init success!
-Disk init
-Tips ------ None Firmware file
-GotoApp->addr=0xC000
-
-start
-[...]
-```
-
-#### 2. Using published source code
-
-If the vendor has published Marlin source code that includes the bootloader, you can search the bootloader source code for the address. Begin your search with the following steps:
-
-1. Find the code that sets the vector table offset
-
-The vector table offset is usually set using a line like this:
-
-```c
-SCB->VTOR = ((uint32_t) APP_START_ADDRESS & SCB_VTOR_TBLOFF_Msk);
-```
-
-Just searching for `SCB->VTOR` should yield some results. From there, you just need to look at the value that's assigned to it. The example uses `APP_START_ADDRESS`.
-
-> [!NOTE]
-> Some vendors publish incomplete source code. But they sometimes leave version control related files in the repo, which can contain previous version of files that were removed. Find these by including folders like `.git` or `.svn` in your search.
-
-> [!NOTE]
-> The example is based on the [Voxelab-64/Aquila_X2](https://github.com/Voxelab-64/Aquila_X2/blob/d1f23adf96920996b979bc31023d1dce236d05db/firmware/Sources/.svn/pristine/ec/ec82bcb480b511906bc3e6658450e3a803ab9813.svn-base#L96) which actually includes deleted files in its repo.
-
-2. Using a linker script
-
-If the repository contains a linker script, look at the memory regions, specifically a region named `FLASH` or similar. The `ORIGIN` of that region will be the application start address.
-
-**Example:**
-
-```ld
-MEMORY
-{
-    FLASH       (rx): ORIGIN = 0x0000C000, LENGTH = 512K
-    OTP         (rx): ORIGIN = 0x03000C00, LENGTH = 1020
-    RAM        (rwx): ORIGIN = 0x1FFF8000, LENGTH = 188K
-    RET_RAM    (rwx): ORIGIN = 0x200F0000, LENGTH = 4K
-}
-```
-
-> [!NOTE]
-> This example is based on [Voxelab-64/Aquila_X2](https://github.com/Voxelab-64/Aquila_X2/blob/d1f23adf96920996b979bc31023d1dce236d05db/firmware/Sources/main/hdsc32core/hc32f46x_flash.ld#L55)
-
-## Documentation on the HC32F460
-
-Due to uncertain licensing (w/r/t STMicro), documentation for the HC32F460 is only available upon request. Documentation includes the following:
-
- Datasheet, user manual, reference manual
- Application notes for the DDL
- DDL source code
- IDE support packages (Keil, IAR, ...) including .svd files
- Programming software
- Emulator / debugger drivers
- Development board documentation and schematics
- Errata documents
- (Limited) sales information
- Full Voxelab firmware source code
- Documents in Chinese or English (machine translated)
-
-Contact me on Discord (@shadow578) if you need it.
-
-## Dependencies
-
-This HAL depends on the following projects:
-
- [shadow578/platform-hc32f46x](https://github.com/shadow578/platform-hc32f46x) (PlatformIO platform for HC32F46x)
- [shadow578/framework-arduino-hc32f46x](https://github.com/shadow578/framework-arduino-hc32f46x) (Arduino framework for HC32F46x)
- [shadow578/framework-hc32f46x-ddl](https://github.com/shadow578/framework-hc32f46x-ddl) (HC32F46x DDL framework)
-
-## Credits
-
-This HAL wouldn't be possible without the following projects:
-
