Hi Alvin,

No this is not possible. Bootloader inside CC3200 have hardcoded 921600b/s and from this reason changing baudrate inside Uniflash not make sense.

Hi Alvin,

This is not possible. When you need flash CC3200 then CC3200 need to be in bootloader mode. Insider bootloader mode is used 921600b/s only. This baudrate is hardcoded inside CC3200 ROM firmware and cannot be changed.

You need to use serial to USB converter which supports 921600b/s.
