I was able to flash using a modified CH340.

After reconnecting the device (with an unmodifed) USB Adapter, the blue led on the ESP8266 is flashing. No WiFi is available.

Does anybody have an idea what could be the reason for that.

thx for support.

Use terminal application like putty with log to file feature enabled.
Options should be same like for flashing but 115200 baud rate.

I have the same problem w/ and ESP-12 and tried several of the 3.2 releases. It looks like the flash worked, the LED blinks about 1/second but there is no ESP-xxx AP to connect to. I tried two different NodeMCUs - same result. I loaded the Example skets that sets up an AP on the ESP8266 and was able to connect to it so I think the WiFi circuitry and antenna is OK.

I tried getting a log at 115200 and have garbled outputs much like the earlier example.

So, a couple of questions:

o Is there a way to connect esp-link to my WiFi network without connecting to the not-visible esp-link AP?

o What can I do to get a better log? The putty display shows very quick lines of text which I can't read and can't be logged successfully at 115200. There are some text characters but not enough to make sense of. small sample:

@profroyk The bootloader messages are sent at a baud rate of 74880. Try to receive the boot log at that rate to read it.

blank.bin is to erase data and esp_init_data_defaults is to init this memory with defaults.

try this file, but decompress it with 7zip tool 3x, it is 3 times compressed zip,gzip,tar
esp-link-v3.2.47.alpha.24-g74e2043-dirty-Lucjan.tgz.zip

try first:

python esptool --port COM7 --baud 115200 write_flash --flash_freq 20m --flash_mode dio --flash_size 32m 0x1000
user1.bin 0x0000 boot_v1.7.bin 0x3fc000 esp_init_data_default.bin 0x3fe000 blank.bin

check if it work
2nd check this one:

python esptool --port COM7 --baud 115200 write_flash --flash_freq 20m --flash_mode dio --flash_size 32m 0x1000
user1.bin 0x0000 boot_v1.7.bin 0x3fc000 esp_init_data_default.bin 0x3fe000 blank.bin 0x80000 esp_init_data_default.bin

Hi everyone,
I have exactly the same problem and the fashing of the 3.2.47 alpha did not fix the issue for me. I am using the Expressif donwload tool.

here are the outputs for the 3.2 and 3.0 versions

2nd boot version : 1.7(5d6f877)
SPI Speed : 40MHz
SPI Mode : QIO
SPI Flash Size & Map: 4Mbit(256KB+256KB)
jump to run user1 @ 1000

rf_cal[0] !=0x05,is 0xFF

ets Jan 8 2013,rst cause:2, boot mode:(3,7)

load 0x40100000, len 2592, room 16 tail 0 chksum 0xf3
load 0x3ffe8000, len 764, room 8 tail 4 chksum 0x92
load 0x3ffe82fc, len 676, room 4 tail 0 chksum 0x22
csum 0x22

And

2nd boot version : 1.6
SPI Speed : 40MHz
SPI Mode : QIO
SPI Flash Size & Map: 4Mbit(256KB+256KB)
no GPIO select!
jump to run user1 @ 1000

rf_cal[0] !=0x05,is 0xFF

ets Jan 8 2013,rst cause:2, boot mode:(3,7)

load 0x40100000, len 2408, room 16 tail 8 chksum 0xe5
load 0x3ffe8000, len 776, room 0 tail 8 chksum 0x84
load 0x3ffe8310, len 632, room 0 tail 8 chksum 0xd8

Can anyone explain what is the issue and propose a way to fix for a newbee like me ?

First try with DOUT flash mode

@bgrigoriu
Copy link

Hi, Thanks

Tried, does not work better. Flassing goes well with eithr DIO or DOUT (ESP flashing tool 3.9.2) but when booting it goes in the same loop.
Same serial output as before

@bgrigoriu
Copy link

I really do not understand what is happening.
If I read well the log:

  • it launches the bootloader which seems ok
  • i do not understand well the " no GPIO select !" but nevertheless it handover to user code @ x01000
  • then it load three "things " then reboots ?
    why so ?
    I may be dumb but I am at the very begening and want to learn.

If it is 32Mbit, you can try to use full flash attached in my previous posts

No it is a plain 8Mbit .
It worked a few months ago and I really do not understand the issues.
Can you give me the link to the " full flash" ?

Tried to flash the 3.2.47 but stil the same issue
I also tried to flash user2.bil to 81000 . Flash ok but then same issue.
Could it be because of the expressif download tool 3.9.2 ?? this is the only thing a changed from last time ?
I really do not understand why
