Re: Unable to flash ESP32

Well, I got it to work already. Turns out it was my USB setting on VirtualBox. I was using USB 2.0 (EHCI) controller. Apparently, it only works with USB 3.0 (xHCI) controller. Hmmm... Thanks a lot for your help nonetheless! Do you mind explaining why I should not connect the USB UART's 3.3V to ESP32...

Re: Unable to flash ESP32

Sorry for my lack of information. I'm using ESP32-Wroom module. I soldered jumper wires directly onto the module and plug the TX and RX jumpers into a FTDI 232H module which i used to flash the ESP32. I am using a Linux Ubuntu 16.04.1 LTS running on VirtualBox using Windows 10 Education. I was able ...

Unable to flash ESP32

Hey guys, I am having trouble to flash the ESP32 after updating to the latest esp-idf. After i used "make flash", these 2 errors occur pretty often: [b]A fatal error occurred: Failed to write to target RAM (result was 0x1, 0x7, 0x0, 0x0)[/b] ~/esp3/esp-idf/components/esptool_py/Makefile.projbuild:47...

UART Parity bit missing

Hey guys, I have been playing with ESP32 module for the past few days. I have gotten around activating UART1 using IO 9 (RX) and IO 10 (TX). The following code is my UART setting: int uart_num = 1; //uart port number uart_config_t uart_config = { .baud_rate = 19200, //baudrate .data_bits = UART_DATA...
