Building for ESP32

[bazooka07]

Hello
I have build myself Espruino.
But when i boot the esp32, I have the following message in the terminal :

rst:0x1 (POWERON_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT)

Where can I change the size of partition ?
I can't find partitions.csv for esp-idf.

Take a look to https://github.com/espruino/EspruinoBuildTools/tree/master/esp32/build/app BTW which version of ESP-IDF is used for your binary ? Am Mo., 3. Feb. 2020 um 22:38 Uhr schrieb bazooka07 < notifications@github.com>:

Release 3.3 for esp-idf with Ubuntu 19.10

[davidbozo]

Same problem here.
Is it some kind of bug or just the binary growed out the partition?
And if i see right in the docs espruino does not support OTA updates. So, could we use the ota partition for the app like this:?

#Name,Type,SubType,Offset,Size
#boot,data,0,0x1000,4K
#reserved,0,0,0x2000,24K
#partition,data,0,0x8000,4K
nvs,data,nvs,0x9000,12K
otadata,data,ota,0xC000,8K
free,data,0x40,0xE000,8K
factory,app,factory,0x10000,2688K
flash,data,0x40,0x2B0000,64K
js_code,data,0,0x2C0000,256K
storage,data,0,0x300000,1024K

And the other problem is i'm not sure how to achieve this. I found one partition csv under:
target/esp32/Changes_V3.1/partitions_espruino.csv
But it looks like it's just a changelog maybe?
As @jumjum123 mentioned there is a EspruinoBuildTools which contains another csv but where i can find it? It looks like the source scripts/provision.sh ESP32 downloads it but here? I'm kind of confused.

[jumjum123]

I'm sorry, just in vacation on canary island. Short feedback: - binary size was growing from version to version. We started somewhere around 800 - latest version tused was 3.1.3 There have been many changes in later versions of ESP-IDF. I could not see any changes, which could be helpful for Espruino. So my decision was follow future versions with low(no) priority only. May be somebody will give it a try once V4 is released ;-) - AFAIK, OTA was never implemented/used - latest csv I used was in https://github.com/espruino/EspruinoBuildTools - Wilberforce supported buildtools, I did not follow to see what changes he did. Latest change was switch to ESP-IDF V3.1.3 - provision.sh downloads a lot from buildtools, but no csv. It downloads compiled .bin for provision Hope, this helps a bit Jürgen Am Do., 13.

No problem thank you for your answer. I was able to build a new partition binary without OTA partition and it works fine.

[cascornelissen]

@davidbozo, can you describe your steps to successfully flash your ESP32? I'm running into the same problem but I'm not sure how to build a partition binary without an OTA partition.

[MaBecker]

No problem thank you for your answer. I was able to build a new partition binary without OTA partition and it works fine.

@davidbozo would be great if you share your knowledge, because we are short on ESP32 know how, since @wilberforce stoped working for Espruino on ESP32 ( I hope he is fine).

[davidbozo]

It's maybe a little hacky solution but there is no porblem with it yet.

So, what i could figure out is:
When we run this script: source scripts/provision.sh ESP32
It downloads binarys from this repo: EspruinoBuildTools
This repo contains the partitions_espruino.bin and when building espruino it's just copies this file.
So to change the partition table this EspruinoBuildTools project has to be rebuild and overwrite the old partitions_espruino.bin in the app/ folder with the new.
(This 'app' folder will be created after running provision.sh)

To rebuild the repo:
After cloning it modify this esp32/build/app/partitions_espruino.csv file:

#Name,Type,SubType,Offset,Size
#boot,data,0,0x1000,4K
#reserved,0,0,0x2000,24K
#partition,data,0,0x8000,4K
nvs,data,nvs,0x9000,12K
otadata,data,ota,0xC000,8K
free,data,0x40,0xE000,8K
factory,app,factory,0x10000,1344K <-- change the 1344K size to 2688K
ota_0,app,ota_0,0x160000,1344K <-- delete this line
flash,data,0x40,0x2B0000,64K
js_code,data,0,0x2C0000,256K
storage,data,0,0x300000,1024K

https://github.com/espruino/EspruinoBuildTools/tree/master/esp32
Here is some documentation at the bottom of the page. But instead of source ./build-idf.sh you can run source ./build-partition.sh in the build folder which is enough as far as i remember.

Sorry, this is what i remember and i can't repeat and test the steps only in work.

[MaBecker]

Ok, let's fix this.

• add firmware size check like we use in ESP8266

• provide a new partitions_espruino.bin

#Name,Type,SubType,Offset,Size
#boot,data,0,0x1000,4K
#reserved,0,0,0x2000,24K
#partition,data,0,0x8000,4K
nvs,data,nvs,0x9000,12K
otadata,data,ota,0xC000,8K
free,data,0x40,0xE000,8K
factory,app,factory,0x10000,1536K
#free2,data,0x40,0x190000,1536K
ota_0,app,ota_0,0x190000,1536K
flash,data,0x40,0x310000,64K
js_code,data,0,0x320000,256K
storage,data,0,0x360000,896K

edit: keep ota_0

[cascornelissen]

How fortunate... Decided I wanted to spent some time on this this evening and I just noticed the comment and commits to EspruinoBuildTools by @MaBecker. Pulled and build everything once more with the new changes and Espruino on my ESP32 is now working.

Thanks a lot for the changes @MaBecker, you rock! ❤️

[MaBecker]

Cool, so you can build and it works for you, thanks for testing!

there are just two more things missing boards/ESP32.py and make/targets/ESP32.make just working on it.

[cascornelissen]

Yeah, it's building for me without any additional changes (I actually removed everything and cloned the repository again just to check) and the error in the original post that I was running into before is gone on my side. Ran a small script to test if that works as well and that seems to be good too 👍

[MaBecker]

Just created a pr for the additional required updates

433708f

[MaBecker]

I guess it will not pull down the new app.tgz version

Espruino/scripts/provision.sh

Lines 76 to 80 in 433708f

	if [ ! -d "app" ]; then
	echo installing app folder
	curl -Ls https://github.com/espruino/EspruinoBuildTools/raw/master/esp32/deploy/app.tgz | tar xfz - --no-same-owner
	#curl -Ls https://github.com/espruino/EspruinoBuildTools/raw/ESP32-V3.1/esp32/deploy/app.tgz | tar xfz - --no-same-owner
	fi

@gfwilliams any hints how to handle updates of app.tgz ?
