Question & Answer
Total 2 questions
Q: I have got the board but having some issues with deploying the micropython firmware. 9600 or 115200 baud rate doesn't allow me to prompt. What should I do? Questioned by musawi, 03-Mar-2020
Q: By default, UART0 outputs some printed information when the device is powered on and booting up. The baud rate of the printed information is relevant to the frequency of the external crystal oscillator. If the frequency of the crystal oscillator is 40 MHz, then the baud rate for printing is 115200; if the frequency of the crystal oscillator is 26 MHz, then the baud rate for printing is 74880. If the printed information exerts any influence on the functionality of the device, it is suggested to block the printing during the power-on period by changing (U0TXD, U0RXD) to (MTDO, MTCK) Questioned by orionsanta007, 22-Jan-2021
