cc2538 bootloader 支持usb调用吗?
Susan Yang:
The boot loader does not support UART over USB. If for some reason you cant use the smartrf06 board and need to use the boot loader through USB you will need to write your own custom Boot Loader firmware. Another option that you have is to buy a USB to UART converter and wire it to the UART pins in the CC2538.

你好:
请教一下,在D:\Texas Instruments\Z-Stack Mesh 1.0.0\Projects\zstack\Utilities\BootLoad\CC2538目录下有两个文件夹,分别是CC2538和CC2538ZNP,有何区别呢?是否里面就是bootloader的源码?
