How to setup a loopback test of uart speed

As the esp8266 uart speed can be set up to 115200*40( that is around 4.5Mbps), we can setup a uart loopback test like this. in uart.c LOCAL void ICACHE_FLASH_ATTR uart_config(uint8 uart_no) { if (uart_no == UART1) { PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO2_U, FUNC_U1TXD_BK); } else { /* rcv_buff size if...

Re: AT and IoT_Demo firmware not functioning

ets Jan 8 2013,rst cause:2, boot mode:(3,4) load 0x40100000, len 23304, room 16 As far as I know, this print log is mostly caused by the spi flash r/w mode mismatching. The default setting is that the spi flash port works in quad r/w mode , if the flash do not support this mode , the chip can not b...

Re: Request for the new command - change baudrate

Maybe you can try to add your own CMD in the AT SDK, and change the baudrate via uart_div_modify(uart_no, UART_CLK_FREQ / (Your_baut_rate)); maybe there should be some sync steps . and reset uart tx rx fifo : SET_PERI_REG_MASK(UART_CONF0(uart_no), UART_RXFIFO_RST | UART_TXFIFO_RST); CLEAR_PERI_REG_M...
