Build and deployment issues with olimex-iot-firmware-esp8266

[meinereiner]

Hi,

I'm experimenting with the "olimex-iot-firmware-esp8266" and as a start I just want to build and deploy a version.

When I just deploy a prebuild version, everything is working like a charm:

Code Select Expand

esptool/esptool.py --baud 576000 write_flash 0x00000 bin/boot_v1.5.bin 0x01000 bin/upgrade/EVB_ONLY/user1.2048.new.3.bin 0x81000 bin/upgrade/EVB_ONLY/user2.2048.new.3.bin 0x100000 bin/blank.bin 0x1FC000 bin/esp_init_data_default.bin 0x1FE000 bin/blank.bin --flash_size 16m
The board boots up and I can connect to it an use the REST interface.

When I'm taking the source code as it is from GitHub and just build it:

Code Select Expand

make clean && make APP=1 && make APP=2
(I do not build it for a specific device, I habe also tested it to build up for EVB_ONLY)
Then uploading it:

Code Select Expand

esptool/esptool.py --baud 576000 write_flash 0x00000 bin/boot_v1.5.bin 0x01000 bin/upgrade/user1.2048.new.3.bin 0x81000 bin/upgrade/user2.2048.new.3.bin 0x100000 bin/blank.bin 0x1FC000 bin/esp_init_data_default.bin 0x1FE000 bin/blank.bin --flash_size 16m
From the serial console it doesn't look strange so far. I only do not see the Wifi. When I reboot the device endy up in an endless loop.

I have also tried to upload user2 via the HTTP. Same.
I also tried just to upload the two newly build files. Same.

What am I doing wrong?

Is the one that fails bigger (for example)?

Otherwise you could use diff etc to find what's changed.

Can you compare your binaries with those from https://github.com/OLIMEX/olimex-iot-firmware-esp8266/tree/master/bin/upgrade/EVB_ONLY

Are they the same or different?

How you setup your toolchain?

I'm currently using https://github.com/pietrushnic/esp-open-sdk

[meinereiner]

Thanks for your answers!

I'm currently using a docker image to build the files:
https://github.com/vowstar/esp8266
https://hub.docker.com/r/vowstar/esp8266/
I had some issues on local installation on conflicting libraries on my machine so I've chossen the docker image.

I have configured the SDK_BASE manually to ensure that I'm using the sources of 2.0.

Why so ever, the reulting bin files do differ (compared to https://github.com/OLIMEX/olimex-iot-firmware-esp8266/tree/master/bin/upgrade/EVB_ONLY) when I build it by my own.

Any idea why?

[PeteW]

I had similar issues when moving my environment to a different computer. I tried using toolchain from https://github.com/pfalcon/esp-open-sdk and result was the same you describe.

Using https://github.com/pietrushnic/esp-open-sdk solved my problem.

[meinereiner]

@PeterW: Thanks for your hint. I will give it a try.
Stupid question: Did you just clone it and set the PATH variables correctly or did you do other things as well?

[PeteW]

As I remember

1. I cloned it
2. build it make STANDALONE=y (it took about 25-30 minutes)
3. manually set the path.

[meinereiner]

Ok I have checked it out and compited it again and uploaded via website just user2. Same.

By the way: old way as well as new way tells me when I upload in the last line on the console a wdt reset:

Code Select Expand


ets Jan  8 2013,rst cause:1, boot mode:(1,7)


ets Jan  8 2013,rst cause:4, boot mode:(1,7)

wdt reset


[PeteW]

Can you try

Code Select Expand

esptool/esptool.py \
--port /dev/ttyUSB0 \
--baud 576000 \
write_flash \
0x00000  bin/boot_v1.6.bin \
0x01000  bin/upgrade/user1.2048.new.3.bin \
0x81000  bin/upgrade/user2.2048.new.3.bin \
0x100000 bin/blank.bin \
0x101000 bin/blank.bin \
0x102000 bin/blank.bin \
0x103000 bin/blank.bin \
0x1FC000 bin/esp_init_data_default.bin \
0x1FE000 bin/blank.bin \
--flash_size 16m

There are some changes in esp_init_data_default.bin for version 2.0.0 of the SDK

[meinereiner]

Unfortuantely the same...

The new flash script doesn't accept "--flash_size 16m" anymore.

Just to sum it up again what I did:
- I have downloaded and build the toolchain with the link mentioned above (esp-open-sdk). I added that path where the toolchain is to the PATH
- I have checked out the Olimex project from github
- I placed the SDK 2.0 in the tools folder
- I have build APP=1

Code Select Expand

make SDK_BASE=".../tools/ESP8266_SDK" FLAVOR="release" APP=1
- I have build APP=2

Code Select Expand

make SDK_BASE=".../tools/ESP8266_SDK" FLAVOR="release" APP=2
- I have uploaded:

Code Select Expand

.../esp-open-sdk/esptool/esptool.py --port /dev/ttyUSB0 --baud 576000 write_flash 0x00000  bin/boot_v1.6.bin 0x01000  bin/upgrade/user1.2048.new.3.bin 0x81000  bin/upgrade/user2.2048.new.3.bin 0x100000 bin/blank.bin 0x101000 bin/blank.bin 0x102000 bin/blank.bin 0x103000 bin/blank.bin 0x1FC000 bin/esp_init_data_default.bin 0x1FE000 bin/blank.bin

Then the reset happens!
[Remark: I have just shorted my path with ... in the example above]



EDIT:
By the way: When I build the entire files:

Code Select Expand


Generate eagle.flash.bin and eagle.irom0text.bin successully in folder bin.
eagle.flash.bin-------->0x00000
eagle.irom0text.bin---->0x40000

and flash them:

Code Select Expand


...esptool/esptool.py --port /dev/ttyUSB0 --baud 576000 write_flash 0x00000  bin/eagle.flash.bin 0x40000  bin/eagle.irom0text.bin
]
Then the device is in an endless loop as well, but a different one. I only see tons of bytes beeing send out via UART.

[PeteW]

olimex-iot-firmware-esp8266 includes SDK 2.0.0 there is no need overwrite the SDK. There are minor changes in our makefiles.

Can you try it without replacing the SDK.

Code Select Expand

make clean
make DEVICE=EVB_ONLY APP=1
make clean
make DEVICE=EVB_ONLY APP=2


[meinereiner]

It is still sontstantly resetting when I flash:

Code Select Expand

.../esp-open-sdk/esptool/esptool.py --port /dev/ttyUSB0 --baud 576000 write_flash 0x00000  bin/boot_v1.6.bin 0x01000  bin/upgrade/EVB_ONLY/user1.2048.new.3.bin 0x81000  bin/upgrade/EVB_ONLY/user2.2048.new.3.bin 0x100000 bin/blank.bin 0x101000 bin/blank.bin 0x102000 bin/blank.bin 0x103000 bin/blank.bin 0x1FC000 bin/esp_init_data_default.bin 0x1FE000 bin/blank.bin
The bins user1 and user2 are build with

make DEVICE=EVB_ONLY APP=...

It looks OK. I'm out of ideas for now. I'll try to reproduce the problem with clean install. This can take some time.
