Hi The interface assignments are redefined so basically we have no UART access at all unless we put it into Flash Mode. No need to erase, just select the files / addresses and ensure the necessary checkboxes are ticked etc and flash as before but using DOUT. Admittedly a long shot...... I'll look at...

Hi As mentioned before, info on these components is hard to gather, but from some posts it is suggesting that certain modules won't handle later firmware as the UART pins change. They mention you can possibly modify the firmware and reassign pins, but I have no experience of this. The posts inform t...

Hi

I ask as the check boxes on the left aren't checked on v2.3

Regards

Hi

Just to be clear, after you erased you then flashed using flash tool 2.3 as before?

Regards

Hi My log files are different to yours and I now know why. The only way I can replicate logs similar to yours is if I skip steps. If I open Flash Tool then download straight away, not testing first or double checking values and selecting files, then I get a log similar to yours (Flash tool remembers...

Hi

I have the feeling that we are overlooking something simple, which is why I'm asking "stupid" questions as many times I've overlooked something simple.

I might not get a chance to compare logs tonight, but I will when I get the chance.

Regards

Hi

Again, stupid question. Did you reset the esp and close Flash?

Regards

Hi No real need to unplug the adapter but you do need to close the flash tool and also reset the esp. There is a slight chance that when you unplugged the adapter and then reinserted it assigned a different port (unlikely) but if you hadn't reset (or removed power then repowered) the esp it would st...

Hi I'll compare against mine later tonight. If it is jumping to DIO by itself then it is overiding the setting of QIO as SpiAutoSet is checked. Not sure why it is choosing DIO over QIO. Maybe try it without SpiAutoSet checked? Stupid question time (as in your earlier post it did look as though you l...

PS

Try using QIO for SPI Mode, not DIO

Hi

Unfortunately a screenshot of a partial log isn't of much help here.

Can you copy the log and paste into a text / word documents and send that?

Regards

Hi That's good you are getting the responses documented in your post. You are almost there. You forgot however to enter the correct Hex values in the Address boxes File / Hex Address blank / 0xfb000 esp_init_data_default_v08 / 0xfc000 blank / 0x7e000 blank / 0xfe000 boot_v1.7 / 0x00000 user1.1024.ne...

Hi Good to hear you have identified the issue. When you are ready to try again, do the following but if any fail, don't move on- 1) Connect to module using "Terminal" and ensure you can send AT and receive OK. If not check why. Once working take note of comm port being used. 2) Close "Terminal" and ...

Hi

Happy to help where / if I can.

Double check connections and also comm port. Numerous times I have forgotten to set it correctly

Regards

PS

If you can use Terminal to connect and successfully issue "AT" commands, take note of the comm port used, close Terminal, then open flash tool and select the same comm port.

Hi From your screenshots you are not connecting to the esp8266. 1) Have you set the correct comm port? Nothing else can be using it at the same time. Close Terminal or anything else that may be using it. 2) Did you press and hold reset, then flash, then release reset, then release flash before press...

Hi There is absolutly tons of info on the esp8266 out there, some good, some bad and some terrible and it is a bit like herding cats. I doubt if there ever will be a fully comprehensive guide to them, rather some "good suggestions to try" :lol: Espressif seemed to subcontract / licence out manufactu...

Hi

Yes, it is the same blank file, just used in various places as referenced by the Hex.

Regards

Hi OK, back in action. I had to completely reinstall to bring the esp of last night back to life. Looking around it seems things have changed a bit since i last played with these and I'm unsure as to why the latest SDK shows 3.0.5 but I can only see 3.0.4 on the website. I doubt if it matters too mu...

Hi

I don't recall the flash tool looking like that. Maybe they have updated it? I'm always wary if espressif make any change which is why if I have something that works I keep a copy of it locally.

I'll look out which version I used and get back to you.

Regards

Hi

My ESP8266 doesn't do anything, possibly the duff one from an earlier post.

I'll grab another, hopefully tomorrow.

Regards

Hi

I've dug out my esp8266 modules and I'll refamiliarise myself with the process. I'll update once done.

Regards

Hi

Not had a chance to check yet but hopefully I can tomorrow.

Regards

Hi

I'm not at a machine with the esp stuff on it but will check when I can

Did you remember to enable the esp first by connecting as per the circuit earlier, and pressing the rest/gpio-0 buttons? Only after that can you then press Start in the Flash tool.

Regards

Hi I'm unsure of your screenshots above and can only comment on what I used. A few posts above I posted a link to download the SDK. If you follow that you are taken to an espressif page and near the bottom you will see a box marked attachments and a link to download the zipped SDK. Download this the...
