@ -61,17 +61,6 @@ this board uses a STM32F103C8T6 micro-controller.
since the device is firmware protected (against read-out), you will first need to remove this protection using an SWD adapter and running `rake remove_protection`.
you can then flash the bootloader using SWD and application using DFU a documented in the section below.
The ST-LINK V2 mini clone has SWD test points on the board.
Because read protection is enabled, you will first need to remove the protection to be able to flash the firmware.
To remove the read protection (and erase flash), run `rake remove_protection` while a SWD adapter is connected.
The Altera USB-Blaster clone has a pin header for SWD and UART1 on the board.
SWD is disabled in the main firmware, and it has read protection.
To be able to flash using SWD (or the serial port), the BOOT0 pin must be set to 1 to boot the system memory install of the flash memory.
To set BOOT0 to 1, apply 3.3 V on R11, between the resistor and the reference designator, when powering the device.
The red LED should stay off while the green LED is on.
Now you can remove the read protection (and erase flash), run `rake remove_protection` while a SWD adapter is connected.
