Hello, I am new here. Sorry for my bad english i am spanish. Ok, i have a ESP-01, but don´t flash the firmware. The led blue is constanly ON, and send to pc junk data. I use arduino uno to flash the esp. The process finish Ok, but dont start and the blue led is always ON, dont Blink. Help Please

see the wiki on this page (scroll up) it'll be bad power , or connections I'd say

Did you connect GPIO0-GND, then reset the ESP and then disconnecting GPIO0/GND before flashing the ESP with the arduinoIDE?

Hm Thats odd when I write the code to my chip ,to put it in UART mode, I hold GPIO0 low all the time , during the upload also.
Once uploaded the code will run with the board unchanged until an intentional or unintentional reset . Then I have to take GPIO0 high and power off and on to start the program running and it runs as intended in FLASH mode.
