- Sat Dec 30, 2017 3:15 pm #72789 Hi, I am new to this forum, and I am not English, so I am sorry if i write something in bad way, but my English isn't perfect.
Yesterday I got LoLin NodeMcu v3 and I wanted to test it at once. I used the NODEMCU FIRMWARE PROGRAMMER programm to flash my board (https://github.com/nodemcu/nodemcu-flasher). When I plugged my board to USB port, nothing happened, so I pushed the FLASH button, clicked the RST button, then I got COM7 port in my computer, so I set baud to 9600 in the program, I put the .bin file (generated here: https://nodemcu-build.com/) into the program, I clicked flash in the program, and then realased the FLASH button on the board. It looked like everything flashed well, but my computer still cannot see my board, unless I set it to flash mode, and when I set it on flash mode, open the COM7 port, and set baud to 74880, then i got this:

Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,2)

load 0x40100000, len 28740, room 16

I get nothing exept of some strange signs when I use 9600 baud. I'll add, that I tried flashing my board using different bauds: 9600, 230400, 115200. The program never shown me any error, always everything goes well, but i Get nothing on derial port, an also ESPlorer cannot connect with my board. I mean it doesn't show any error, but just connets and connects and does not finish connecting...
I'm using Windows 7 Home Premium, and I've got CH340G driver.
I thing I wrote everything that is important, if you need to know enything more, just ask me.
Thanks in advance for help.
