Here is the meta-intel-edison that builds, tries to stay up to date. Master is based on Yocto Poky Gatesgarth LTS 5.10.yy vanilla kernels. It builds a 32bit kernel (Gatesgarth branch 64bit) with ACPI enabled and corresponding rootfs. Telegram group: https://t.me/IntelEdison Web-site:

i2c not work in master #73

Closed xlla closed 4 years ago

xlla commented 4 years ago

Hi, I am very excited to found this wonderful project! It make my Edison board reborn. I have successful build branch sumo and branch master. but I can't get my i2c device work with it. I have read each section of manual very careful, and can't find a clue. I am use Edison Arduino board, and I had followed guide I2C, there is 4 multiplexers in bus-1, address 20-23, but none device in bus-6, my device is ssd-1306 oled, it works on arduino uno board at address 0x3C, I have found some error message in log:

Welcome to Poky (Yocto Project Reference Distro) 2.6.4 (thud)!

Sure you have sumo? According to last line (thud).

The error lines are prior to mounting rootfs. They originate from initramfs loading acpi tables, I believe this https://github.com/edison-fw/meta-acpi/blob/eds-5.0.0/recipes-bsp/acpi-tables/files/edison/acpi-tables-load. It seems gpiofind is not working. Maybe sleep 0.1 is just a little too fast?

What do you get when you gpiofind TRI_STATE_ALL from the command line?

xlla commented 4 years ago

it's a long story, I have built sumo first, and then I have found i2c can't work, so I think it maybe caused by ACPI, then I have created another env and switch to master branch and built thud.

it return nothing root@edison:/media/sdcard/git/luma.examples# gpiofind TRI_STATE_ALL root@edison:/media/sdcard/git/luma.examples# gpiofind TRI_STATE_ALL

it's a long story, I have built sumo first, and then I have found i2c can't work, so I think it maybe caused by ACPI, then I have created another env and switch to master branch and built thud.

env has nothing to do with this. There is a no-acpi branch (sumo32) that makes mraa/upm working by adding a kernel patch. So i2c works. https://edison-fw.github.io/meta-intel-edison/0.6-News.html#whats-new-for-this-release

In the acpi enabled version (sumo64-acpi, thud, thud32-v2.0), i2c works too. But not through mraa, mraa needs to be patched. Here we select which acpi tables to load (leds!) and what stuff to enable (i2c!): https://github.com/edison-fw/meta-intel-edison/blob/master/meta-intel-edison-bsp/conf/machine/edison.conf

it return nothing root@edison:/media/sdcard/git/luma.examples# gpiofind TRI_STATE_ALL root@edison:/media/sdcard/git/luma.examples# gpiofind TRI_STATE_ALL

That is not normal. I am on warrior now (there is only an acpi enabled version now).

root@edison:~# gpiofind TRI_STATE_ALL
gpiochip1 14

I found that built in led in pin 13 don't work, only when I do this rmmod ledtrig_heartbeat rmmod leds_gpio

With leds.asl loaded the kernel takes the led and runs the heartbeat trigger (this beats faster with higher cpu load). With the kernel taking control of the led, you can not access it from user space, so blink-led service fails.

If you don't want leds controlled from the kernel remove it from edison.conf.

led start blink with some warning: root@edison:/media/sdcard/git/luma.examples# blink-led can't find line TRI_STATE_ALL, type=gpiod.LINE_REQ_DIR_OUT can't find line TRI_STATE_ALL, type=gpiod.LINE_REQ_DIR_OUT

Same problem, TRI_STATE_ALL doesn't exist.

I have connect second spi oled, it does not work too. root@edison:/media/sdcard/git/luma.examples# ls /dev/spi* /dev/spidev5.1 python3 examples/demo.py -i spi --spi-device=1 --spi-port=5 --gpio-data-command 41 --gpio-reset 49

I don't know this demo. Maybe something else is wrong. But note, in ACPI_FEATURES_edison ?= "uart_2w i2c" spi is not enabled. And you can't combine spi and leds.

Do you have the same if you power down the edison (pull the power cord) instead of pushing reset (cold v.s warm boot).

That will be most welcome.

Actually it is the acpi table leds.asl that defines the control (hogs the gpio). You can find the acpi tables here: https://github.com/edison-fw/meta-acpi/tree/eds-5.0.0/recipes-bsp/acpi-tables/samples/edison.

#KERNEL_MODULE_AUTOLOAD += " ledtrig-heartbeat"

This module only tells the kernel how to blink the led device. We have other ledtrig as well.

KERNEL_MODULE_AUTOLOAD += "fbtft_device"

We do have display acpi tables, but I don't know how to use/create them. @andy-shev knows of course.

#module_conf_fbtft_device = "options fbtft_device name=er_oled028 busnum=5 debug=7

> `#ACPI_TABLES ?= "arduino.asl spidev.asl leds.asl"` >` ACPI_TABLES ?= "arduino.asl spidev.asl"` This will load these 2 tables and the LED pin will be available. > `ACPI_FEATURES_edison ?= "uart_2w i2c spi"` This sets conditional for building the tables.

There is a jumper to select 3V / 5V operation. What does your device need? Also: TRI_STATE_ALL must be high. You could try this before i2cdetect: ``` gpioset `gpiofind TRI_STATE_ALL`=0 gpioset `gpiofind TRI_STATE_ALL`=1 ```

my device can tolerate 3v-5v, so I just left jumper to default location, I think it's 5v.

htot commented 4 years ago

It may be that documentation can be improved. We take patches for that too. You can find mark down here: https://github.com/edison-fw/meta-intel-edison/tree/master/docs/_docs/Edison. Github generates https://edison-fw.github.io/meta-intel-edison/ from that.

xlla commented 4 years ago

it work! amazing! thank you very much! but I am still a little bit confused by what goes on. according to original Intel edison arduino board manual, before we can use i2c , we should pull down gpio214, then select pin-mux, set pin direction, set pin pull-up, and then pull up gpio214.

now I just simple pull down gpio214 and pull up it, everything is done. if I missed anything or kernel prepared everything in between 214 down and up according ACPI table?

htot commented 4 years ago

It's done in the acpi tables. Don't thank me, thank @andy-shev who did the kernel work and the acpi tables.

I think we can close this one?

xlla commented 4 years ago

yes we can! many thanks for @andy-shev 's hard work, and thanks for your patience!

one more thing, I saw there already is a call in recipes-bsp/acpi-tables/files/edison/acpi-tables-load

but when I first login, it was still remain low root@edison:~# gpioget gpiofind TRI_STATE_ALL 0

andy-shev commented 4 years ago

Unfortunaly this discrete pin control on Edison/Arduino expansion board has an (unknown) flaw when I2C GPIO expanders, powered by V_SHLD_IO, are simple disappeared. This requires the cold power off / on cycle. The desing of TRI_STATE_ALL is another flaw on this board. So, we have no mechanisms to set that pin reliably. (In correct design the TRI_STATE_ALL must be a pin of the GPIO which always present in the system, like the main one on SoC). That is, Edison/Arduino expansion board is not recommended for production devices.

andy-shev commented 4 years ago

@htot, may we put the above to some wiki if it's not there? Can you recommend the page where that information suits better to be on?

htot commented 4 years ago

We can put it in the wiki https://github.com/edison-fw/edison-wiki may be create a new page i2c.md?

Or we can put it in the documentation https://github.com/edison-fw/meta-intel-edison/blob/master/docs/_docs/Edison/Current%20State/4.4-hsu-i2c-spi.md

andy-shev commented 4 years ago

@htot, just sent a PR, please consider to merge. Thanks!

htot commented 4 years ago

Thanks, merged that. Edison Wiki should be more or less good to go now and a nice addition to the Intel Edison Image Builder site. Closing this issue.
