On a side note, The instructions should probably be updated or the flash.sh script fixed..
The instructions state that we should:
Execute `./flash.sh -eo -t 1MB -m DOUT` to erase the existing firmware
But when we get to:
Execute `./flash.sh -t 1MB -m DOUT` to flash the new firmware
This also causes erase first. That makes 2 erases before write.
Also, During the second command, we are given a very brief window to reboot device while holding esp8285 boot pin to ground. This can be very tricky. I think that "flash.sh" should be fixed to not perform erase during write action.
Also, All of the steps in the instructions are "#1" lol.
Oh yea, And:
./flash.sh -eo -t 1MB -m DOUT
should be replaced with:
./flash.sh -eo -t 1MB -m dout
Since it will fail with capitals.
Okay, So now I'm about to give up..
Got no wifi connection at all.
Tried to flash back to ESP8285's Original Firmware, from:
http://dl.sipeed.com/MAIX/factory_firmware/esp8266/WiFiSPIESP.ino.esp8285_40M_freq_1M_DOUT.bin and loaded Sipeed's Maix 5.0 Firmware so everything should be stock.
Now When i try to connect to wifi, I get :
Stopped Because: couldn't init nic esp8285 ,try again please
Now i can't get wifi at all. What's wrong here?
It looks the WiFi firmware flash was OK. It is strange that you can't get any response from ESP8285. I'll try to look into it. I'm using M1W for 10 months and newer had a problem.
I supose you have disconnected usb->uart adapter before testing. You can try to init with
wifi.start(tx=7, rx=6, ssid="SSID", password="PASS", baudrate=115200, wait=True)
ESP8285 enable pin is connected to K210 io Pin #8 and pulled-up with 12K resistor. You must newer use Pin #8 while using WiFi. Yo can try to configure the Pin#8 as output and set it high before initializing WiFi (using machine.Pin).
ESP8285 must be initialized even with the original firmware, there should be responses to the commands...
At the moment I can't think of anything else, I'll report if I'll find something.
Thanks for the comments about flashing process. I'll use them to update the instructions for the next update.
I submitted a pull request for changes to Readme.md if you would like to look at it. I will try your suggestions.
So this is what i get on the original firmware:
>>> fm.register(8, fm.fpioa.GPIOHS0, force=True)
1
>>> wifi_en=GPIO(GPIO.GPIOHS0, GPIO.OUT)
>>>
>>> fm.register(board_info.WIFI_RX, fm.fpioa.UART2_TX, force=True)
1
>>> fm.register(board_info.WIFI_TX, fm.fpioa.UART2_RX, force=True)
1
>>> uart = UART(UART.UART2,115200, timeout=1000, read_buf_len=4096)
>>>
>>> wifi_en.value(1)
>>> nic = network.ESP8285(uart)
Traceback (most recent call last):

OSError: couldn't init nic esp8285 ,try again please
I will have to load yours again to see what happens. I'm just confused why if i set everything back to factory it still does not work? I loaded the ESP8285 FW from the link above. 8(
"I'm just confused why if i set everything back to factory it still does not work?" Was it ever working?
"I'm just confused why if i set everything back to factory it still does not work?" Was it ever working?
Yes. Definitely.
now i'm back on your firmware, wifi and k210:

It is impossible to destroy ESP8285 by flashing! But it is possible it was not flashed correctly. You can try some other flashing method.
You can try to attach usb->uart adapter (Rx) to esp8285 Tx (K210 Rx) without connecting adapter's Tx, to see if there is any communicattion, there should be. I think ESP8285 prints some messages after reset (at 115200 bd).
I know it is no longer labeled "DanDock" like the one from the wifi flash readme.md picture. Instead it says "Maix Dock". From our previous problems, it seems they have used slower flash, what else did they change? (rhetorical)

I did try this, I'll do it again and post results.

Does that mean anything to you? LOL
BTW, I tried flashing back to original fw using "flash_download_tools_v3.6.8" from espressif. Didn't seem to make any difference so i went back to esptool. Should I try this to flash your FW?
It also prints this when i go from LOW to HIGH on pin 8 (wifi_en):

Okay, so i watched while it does "Check and set device baudrate" and I get unknown chars. I have no idea what baud it is trying to use. I have tried many possible baud rates and nothing seems to be correct. LMK what you think.
With my firmware flashed, you should get the following messages after esp8285 reset (pin8_lo -> pin8_hi):

The massages after Starting firmware 0, map 2 from 001000... will be wisible only if ESP8285 baud rate was set to 11520 (after that message ESP8285 switches to the stored AT-command baud rate).
The baud rates tried by wifi driver are 115200, 230400, 460800, 921600, 1000000, 2000000
Before starting wifi you can connect usb->uart TX line to ESP8285 and execute AT commands directly from some terminal emulator (minicom, putty)

Yea, I'm not getting anything like that at 115200. I get what I posted. I just reflashed your firmware again too. Seems to be going perfectly. I have tried to communicate at many different baud rates, including the ones listed with no success. Even tried using Arduino IDE serial monitor since i know it can send both LF + CR. When i send "AT" at 115200, i get a response of "!".
This is what i get when booting or when toggle wifi_en.value 0 > 1

I just ordered a new board, maybe i can read the flash from it and flash this one back to stock? IDK.
Hey, i just realized something.. The "ESP DOWNLOAD TOOL" reports that the ESP8285 has:
flash vendor:
51h : N/A
flash devID:
4014h
QUAD;8Mbit
crystal:
40 Mhz
Could this be the issue? 8mbit flash instead of 1mbit? Also, I got new Board today so i will try to read the flash from that and flash it to "broken" board in order to recover.
i feel stupid, just realized that. Somehow i just did esptool read_flash for to 0x800000 tho lol.
Okay, it works again on stock firmware. Just successfully read flash from the new board and wrote it to the old one. Now WiFi works again.

So to recap, I don't think it's something wrong with your frimware, since the frimware posted by Sipeed doesn't work either. I'm going to post this firmware I just read here in case anyone else needs to flash back to stock and finds there is no working firmware available. Google Drive
So now I'm back to stock and wifi works again. I tried flashing the esp8285 with your firmware again and had the same problem. Your firmware simply does not work with my board. When I try to use stock esp8285 firmware with your K210 firmware, I get this message. Any Suggestions? Any ideas to make your firmware work with esp8285?

It looks there is some issue with WiFi firmware provided in this repository's firmware/wifi/upgrade/ directory.
Could you, please, try to flash the firmware from ESP8266_AT_LoBo.
Just clone the repository, change the working directory to at_lobo inside the cloned directory and flash. The flash procedure (and flash script) is the same.
If the WiFi task is not started after the first init (WiFi TASK TERMINATED), just try again with the correct wifi credentials (after the first try some default configuration values are saved).

I'm about to try. I don't have high hopes though since the firmware from sipeed didn't work either, i doubt if it's a problem with both firmwares. More likely (to me) that there was a change in hardware that requires a different firmware which is causing the issue.
I'm quite sure it will work as I've tested it today on a new M1W module, not previously flashed...
