I2C transfer timed out addr: 0x50

Robotics & Edge Computing Jetson & Embedded Systems Jetson Nano

I am developing a custom carrier board for my jetson nano.
I am communicating via UART with my board and this error message is popping up all the time.

[   11.125690] tegra-i2c 7000c700.i2c: pio timed out addr: 0x50 tlen:28 rlen:128
[   11.132835] tegra-i2c 7000c700.i2c: --- register dump for debugging ----

[   11.168004] tegra-i2c 7000c700.i2c: I2C_INT_STATUS - 0x0

I think that this error has something to do with the I2C communication with the EEPROM on my carrier board. I use the same EEPROM as on the NVIDIA carrier board, just in an other package and I set the address to 1010111. When I run sudo i2cdump -y 2 0x57 I get:

How can I solve this communication error between the Jetson nano and my carrier board?

And in the schematics the Pins 232 I2C2_SCL and 234 I2C_SDA should be switched. The data is transfered at pin 232 and not at pin 234. The clock is transfered at pin 234.
I already realized this change on my custom carrier board after I figuered it out.

3

If this is the HDMI monitor query (DDC wire containing EDID data via i2c protocol), and if you didn’t install HDMI, then this might be the problem. Someone else will need to give you an answer, but you probably should describe if you have HDMI on the custom carrier board (and whether you adjusted the device tree for anything non-standard with your HDMI).

4
  1. Are you using the same AT24C02D-MAHM chip?
  2. did you power the chip using 1.8V?
  3. I really don’t think I2C2_SCL and I2C2_SDA should be switched… if that is true then nVidia has huge problem with both schematics and development guide documents. This is usually uncommon. Using scope to probe the signal to make sure you did it right.

PIN232 I2C2_SCL GEN3_I2C_SCL
General I2C 2 Clock. 2.2kΩ pull-up to 1.8V
on the module.
I2C (General)
Bidir Open Drain – 1.8V

PIN234 I2C2_SDA GEN3_I2C_SDA
General I2C 2 Data. 2.2kΩ pull-up to 1.8V
on the module.
Bidir Open Drain – 1.8V

I don’t have an HDMI connector, so these pins of the jetson nano are floating. How can I tell the jetson nano by hardware, that there is no HDMI connector?

  1. I use the AT24C02D-SSHM-T, so the same chip, just in another package.
  2. I’am powering the chip with 1.8V
  3. The Pins are definitely switched. I watched the signals on the oscilloscope and I can read the data of the EEPROM only when the pins are switched. On the NVIDIA carrier board the pins are already switched. I used the multimeter beep test to check that.
6

Thanks,

Can engineer from nvdia confirm this? maybe update the documents and/or errata?

7

I couldn’t give you the details, but if your board lacks HDMI, then you definitely need changes to the device tree.

8

I figuered out how to deactivate the HDMI connection. When no HDMI is connected to the carrierboard the Hot-Plu-Detect Pin is High(1.8V). If you connect a HDMI cable, then it is Low. Therefore I installed a Pullupresitor to 1.8V on my custom carrierboard. The Hot-Plug-Detect Pins of the HDMI and Display Port are also switched in the Schematics. The Pin 88 DP_HPD is connected to the HDMI and not the Diplay Port Module. Therefore the Pin 96 DP1_TXD0_N is connected to the Display Port and not to the HDMI Module.

9

Did that resolve the issue? So long as there is no attempt to run i2c query on non-existent hardware it should be ok regardless of whether HDMI is removed in device tree, or whether a pin is saying to ignore HDMI. Though I suppose if i2c setup occurs there might still be an error.

10

Yes it did resolve the issue.
I still didn’t figure why the Jetson Nano needs an EEPROM on the carrier board. I have a carrier board on my custom carrier board with the address 0x57. I can read and write data from that EEPROM, but the Jetson doesn’t seem to need that EEPROM, because it doesn’t change the data in the EEPROM. Can somebody tell me what kind of data is stored in the EEPROM and when does the Jetson Nano store this data there?

11

Please refer to below topics, eeprom on carrier board is not MUST.

https://devtalk.nvidia.com/default/topic/1065885/jetson-nano/device-tree-and-hpd-issue-with-production-module-with-custom-carrier/post/5403211/#5403211

12

Has anyone at Nvidia confirmed that the pins are, in fact, swapped on the i2c lines. I am also using a custom board, and cannot make it through any i2c setup. I2cdetect will time out with PIO errors for me as well.

13

Hi, can you list the pin need swap? Current docs in DLC is for production module design, its pinout is different to early module (A02).

14

I purchased 5 dev kits from Digikey, and part number on the bottom of the carrier boards is 180-13449-daaf-a02. The carrier board for the module is custom and I did the schematic based on the published ORCAD documents that were available for download from the NVIDIA site. When I checked against the schematics (concept and orcad versions), the layout of my PCBA matches correctly. The HDMI does not read EDID or Hotplug either. Here is the boot screenprint:

Hi Daniel,

indeed, the I2C_2 pins on the A02 module are swapped in comparison to the B01 module. But it looks that some other pins at A02 are placed a bit differently too. Unfortunately, there is no officially available A02 module and DevKit schematics and pin-outs, thus the [A02 SoM + A02 DevKit] cannot be used in custom designs.
Nevertheless, the B01 module is documented correctly.
