Hi,

1. Indeed some clarification on the expansion board in combination with ArmstoneA9R3: I was not fully correct in my statement: the original board had it wired to pin 16 and 17 of the ArmstoneA9R3 board. We meanwhile already rewired a prototype of our…

Hi Didier,

first - an additional question from my side. Your expansion board where I2C TI PCF8574A is mounted works currently in combination with an ArmstoneA9r3? That's stange! As far as I see (all) previous armStones have no I2C option at all on FC.29,…

Hi,

Thanks for the quick response.

Before we get into an RMA, some questions:

1. can you explain me what AIN stands for, what is its purpose?
2. do we have a one-off board or do all the armStoneMX8MP-V22I-LIN SBC's have this AIN on board?
3. if all the…

Hi Didier,

yes this it the right number. So I figure out your baord is configured for AIN not for I2C_D.

a) You can send use the board(s) as RMA for conversation (add these post as referee).
b) I can send you conversation instructions in a separate private…

Hi support,

My serial number is 25890C (assuming you request the number as mentioned on the sticker on the HDMI connector?)

Hello Didier,

what is the serial number of your board?
Assume your board variant is configured for AIN and not for I2C_D becauce address=0x49 belongs to ADS1015 (ADDR=high).

Dear support,

I'm trying to connect an external i2c device to I2C1 on an Armstone IMX8MP board.

I have the following i2c configuration in my dtsi file (I only changed the clock frequency in the original dtsi from 400K to 100K):

&i2c1 {
clock-frequency =…

Hello,
The i.MX6/SX/UL Scarthgap Releases are scheduled for April. There are some issues with U-Boot because we have to switch to the device tree model and our NAND flash sizes are to small for it We will have to introduce some kind of compression for the…

This is the ZephyrRTOS release v4.3.0 for F&S modules based on the i.MX93 SoC.
Currently the PicoCoreMX93 is supported. More boards will follow.

How everything is set up and installed is described on our GitHub page F&S ZephyrRTOS.
There are already some…
