esp-link crashing after bcn 100 command

codehero commented 4 years ago

after flashing v3.0.14 my ESP8266 constantly resets with a "wdt reset" or "normal" error. I have ensure correct flash map and speed.

your flash is 8Mbit (1MB) where did you flashed initial/default settings? should be at 0xFE000

codehero commented 4 years ago

Yes, I used the following command: esptool --port /dev/ttyUSB0 --baud 115200 write_flash -fs 8m -ff 40m 0x00000 boot_v1.7.bin 0x1000 user1.bin 0xFC000 esp_init_data_default.bin 0xFE000 blank.bin

Also flash_id output:

uzi18 commented 4 years ago

@codehero try to add argument -fm dout just after write_flash

check dout first, but before flash anything reflash 1MB blank.bin file at 0x0 to clear all in flash mem

Maarten69 commented 3 years ago

Did you solve this, I have the exact same problem with an ESP-01. I think I can't rely on flashsize from esptool output because that info is overwriten if not mistaking.

Technic1975 commented 3 years ago

Did anyone find the solution to this, I have the exact same problem and it is driving me crazy!

Technic1975 commented 3 years ago

Well I have a further development, although the AP never shows, I have discovered that if I erase the module, then flash the hello server sketch with Arduino 1.8.14 with my SSID and password details included, then flash ESP link over the top, minus the Blank.bin file, I am able to connect to ESP link on my pc over my local network with IP 192.168.0.65 and configure as I like.

I updated the firmware to NMEA link and am able to send GPS data as I had planned, the unit still won't set up an AP though if it cant connect to the specified network.

This is really frustrating as I feel I am very close, does anyone have any Ideas?

uzi18 commented 3 years ago

Have complete flash dump available from working module if anyone is interested

I would very much appreciate it if you could supply this.

here it is: https://github.com/uzi18/sterownik/tree/master/arduino/esp-link next use my update from here: https://github.com/jeelabs/esp-link/issues/480#issuecomment-577457913

Technic1975 commented 3 years ago

here it is: https://github.com/uzi18/sterownik/tree/master/arduino/esp-link next use my update from here: #480 (comment)

Thanks very much, lets see how I get on!

uzi18 commented 3 years ago

First go with full flash erase, next decompress image and flash it with DOUT to 0x0 address if it is working ok you can update with user1 and user2 files from second link

Technic1975 commented 3 years ago

Thanks for that, probably a dumb question, but what do you use to decompress the image file?

Technic1975 commented 3 years ago

Was a dumb question lol, you meant unzip the rar then flash the image, just done it now lets see what happens!

Technic1975 commented 3 years ago

That doesn't work I am afraid, It is stuck in a boot loop, the AP shows up for a second and I can connect to it then it drops out. This is what has happened with all other attempts to flash this.

Well I don't know why, but after many attempts at flashing the image with various different settings in the ESP8266 download tool, with just a constant boot loop, I tried with the SPI autoset check box ticked, and hey presto! I am able to connect to the Lucjan AP and configure via 192.168.4.1, I also updated the FW to the latest version as suggested and this seems to have worked also.

I will keep playing with it to try and figure out what the problem is exactly as the settings it autoset to I had already tried.

Many thanks for your help with this, much appreciated, it's been driving me crazy!

uzi18 commented 3 years ago

It's because of bad quality of spi flashes (DOUT is always supported fallback). Also if you used to high frequency it will not boot correctly, settings are created in flash durring first boot or after update.

Thanks for that, I that would make sense, I had it working but after a while became unstable, I tried to erase and re-flash with exactly the same settings and am stuck back in a boot loop, very frustrating! It could be that this board is faulty, I am going to order another and try again. Thanks for all your help and advice.

uzi18 commented 3 years ago

You can try to change only flash chip or send me your unit so will check on my own.

Technic1975 commented 3 years ago

Well I purchased a second module, same results! after a lot of frustration I have found that if I flash these modules very slowly at 9600 Baud rate that they work just fine, very unstable flash chips! thanks for all your help uzi18.

cquijano commented 3 years ago

Had the same issue with my ESP8266X, 4MB. After a lot of tries and error I found the that the firmware V1.0.4 works fine for me, any other ,more recent version, have this problem. Maybe it is because the build process of this image has a specific image for 4MB.

For me flash speed, makes no difference, I tried at 9600 baud rate too.

uzi18 commented 3 years ago

You can try to change flash chip to 32Mb

What is your flash chip ID?
