Sonoff PN25F08B: Same problem like PUYA

[Micha_he]

My Sonoff Basic/S20 arrived today. Both have a flash PN25F08B from XTX.

Flash the new ESPEasy V2.x on it, produce the same problem like the PUYA-flash.
Flashmode DOUT doesn't change anything...

ESPEasy (V1.x) R148 works fine (like on my PUYA-ESP-01)

It seems these flash chips were causing issues about 7 months ago: viewtopic.php?t=3071
But flashing using Dout doesn't fix it, like you said?

Also when you select DOUT as profile in Arduino IDE, build it and then flash it?

There is a difference in flashing using the flash tool and how the firmware itself will use the flash.
I am not entirely sure how it is being stored in the firmware, so correct me if I'm wrong.
If I remember correctly, somewhere in the first 4 bytes of the firmware, the flash size, speed and IO-mode is being set.
And since the firmware is written starting at address 0, I would expect the firmware itself should contain some information on how the flash should be used by the firmware.
The pre-built firmware files are probably built using DIO and not DOUT.

[Micha_he]

You mean, setup DOUT here....

does not work !?

Can I download somewhere a DOUT-compiled ESPEasy firmware ?
Until now, I have flashed only binary firmwarefiles. Otherwise, I'll have to install an environment for a test.

[TD-er]

I have never used that programmer myself.
So I don't know if that programmer also does something to the firmware.

The only thing I know is that the internal functions, defined in the ESP8266 core libraries try to read some bits from the first 4 bytes of the flash and based on those bits decide how to interface to the flash.
Using those function, the flash information on the info page in ESPeasy is collected.

[TD-er]

I was just looking into the code to do so.

I could try to add something like this to the firmware, to force the flash speed to DOUT:
https://github.com/arendst/Sonoff-Tasmo ... #L174-L194

Then it will permanently set the flash to DOUT mode, which is a little slower (in theory)

You can flash it with the ESP8285 version.

[Micha_he]

Yes, it works with the actual 8285-firmware

But only, when I flash the 8285-(DOUT)-firmware, with a flash-tool like 'NodeMCU ESP8266Flasher', which flash the firmware in DOUT-Mode.
The 'FlashESP8266.exe'-tool that include with ESPEasy doesn't work !

A additional test with my PUYA-ESP-01 unfortunately shows no improvement with this way/firmware

Thanks,...

My flash wrapper (link in my signature below) have an option to force DOUT. If I manage to get it a bit more stable with many different systems we might add it to the official release.

If you add "board_flash_mode = dout" to the section you wish to build in PlatformIO, you get a firmware version that is set to operate on DOUT mode.
Also for reading/writing the flash during operations.

For example:

Code: Select all

[env:normal_ESP8266_1024]
platform = espressif8266@1.5.0
board_flash_mode = dout
framework = arduino
board = esp12e
upload_speed=460800
build_flags = ${common.build_flags} -Wl,-Tesp8266.flash.1m128.ld
# upload_port = /dev/ttyUSB0

I just created a build to test: https://www.dropbox.com/s/5soy1jhoul991 ... T.rar?dl=0

In the info screen the flash speed should show DOUT.

Thanks for that test-image... But what is then the difference to the 8285-image from release-package ?
Is it better for my 8266 on the Sonoff Basic ?

In the info screen the flash speed should show DOUT.

You're speaking in riddles. Which 'info screen' ? From Atom-PlatformIO ?
I'll take a look on PlatformIO on the weekend, when I've more time...

No, info found under the tools tab.

[Micha_he]

No, info found under the tools tab.

Aha, you're mean on ESPEasy-Web-Interface...

Yes

[TD-er]

In ESPeasy web interface:
Tools => info

If I remember correctly, the flash information is located at the bottom of the page for the v2.0 branch.

Ah, should look better, there was a next page

@TD-er:

Yes, your image works (tested with esptool.exe from commndline with option '-bm dout' !!) and displays "Flash IDE mode: DOUT" in the last line of Tools/Info

Nice to hear

I've made an issue for it: https://github.com/letscontrolit/ESPEasy/issues/831
And a pull request: https://github.com/letscontrolit/ESPEasy/pull/834

So next release (when the PR is merged) will have one pre-built image with "normal" + 1MB + DOUT
