Hey guys,

I'm back again with another problem. =/

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 ...

Thank you so much for the prompt reply.

I refered to this hookup guide except that the GPIO0 were connected directly to 3.3V or GND (whenever necessary) instead of using a DIP switch as shown in the picture.

I tried ...

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 ...

i'm using 115200.

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 ...

sweet! thank you so much!

May I know if the bug has been fixed?? I don't see it in the commits.

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 ...
