Hi,
Can I configure the boot loader to load image from serial port like UART?
I want to build my own application and one of the first thing that I need to implement it to have the ability to load image on startup from external chip over serial communication port.
We need to design PCB board and I didn't found any documentation on how to do it.
Hello,
I believe the USB ISP bootloader it's what might work the best for you, this method expects a binary in a certain format described in section 7.6.1 USB firmware structure of the QN908x User Manual. To convert a binary to the expected format you can use the QN908x Image Editor, you can download it from the Lab and Test Software section of the Software and Tools tab.
For the PCB could you please check this link?
