For Flash : just connect

3v3 + EN ---------> 3.3V (From TLL to USB)

(ALL) GND + IO15 ---------> GND

IO0 ---------> GND

Hello Faye

That´s the configuration I am using - MTDO: 0, GPIO0: 0, GPIO2: 1. I have to keep GPIO:0 during the whole process right?
Still I get an error during the programming. This aproximately 4 times out of 10.

Thanks again for your attention,

Javier.

Hi,

To download the bin files into Flash, it should be MTDO: 0, GPIO0: 0, GPIO2: 1.

To run the firmware, it is MTDO: 0, GPIO0: 1, GPIO2: 1.

Thanks for your interest in ESP8266 !

Flash Downloader tools fails often[Done]

2016-03-18T21:57:45+08:00

Dear Sirs,

When I use the flash downloader tool to download the FW in a WROOM-02 module it often fails. I would say 4 out of 10 times I try to update it gives ERROR!.
Has anyone experience something like that. I am using a USB to 3.3V TTL converter to do the job. Is there any consideration in the HW around the WROOM-02 for this task.

Thanks for your comments,

Javier.
