For the first eMMC read of data for upload, use the "large" dfu_buf (now configurable) instead of usb request buffer allocated at composite layer (which is 4KiB) [*]. For eMMC the whole file is read, which usually is larger than the buffer [*] provided with usb request. Signed-off...

为什么要使用mcubooot,原因是在NCS使用mcuboot,可以很快的实现DFU的加入,可以同时加入ble-dfu和uart-dfu。就是加入几个宏定义的事情,就完成了在SDK中可能要花很久才能完成的工程移植,既有ble也有uart的升级。 二、nRF bootloader升级程序制作(不推荐这种方式) ...
