LPC5460x USB Secondary Bootloader using YModem

[spu12kimo]

請教一下

有像
AN12384
LPC5460x UART Secondary Bootloader using YModem
文件一樣，將
1.UART接口改為USB接口使用 Bootloader

2.使用MCUXpresso IDE v11.0.1產生燒錄檔
是否有說明的文件，或範例可以參考

謝謝

Chapter 3: LPC546xx Boot process

Hi 寶凱 李

We don't have exact USB CDC secondary bootloader demo code.

But you can refer SDK USB CDC demo code to develop your secondary bootloader CDC driver .

usb cdc demo is included in MCUXpresso SDK package.

Have a nice day,
