I am running the PSoC 6 MCU Basic Device Firmware Update(DFU) example (CE213903) and it works when the baud rate of the UART is set to 115200.
It takes about 30 seconds to do the update using the Bootloader Host though. For my application I need to get this upload to under 6 seconds.
I tried increasing the UART speed to 921,600 in the UART in the top design, and the setting the Bootloader Host to run at the same but I get the error "Communication port reported error 'Unable to read data from the target device'."
Any idea why I can't increase the UART speed?
It's just because the max supported Baud rate speed of USB-UART Bridge is 115200 for all available PSoC 6 DVKs.
