Hello, I am having trouble understanding how to map the physical pins on the 40-pin rpi compatible header (iPi Smarc Elkhart Lake) to their respective I/O addresses. The manuals for some of the bo...

Dear @Riccardo Benedetti, our support team is investigating the issue. Because this is a BSP build issue that is complicated, I would recommend that you to create a "Ask An Expert" ticket to file t...

Hello @Kothandaraman Kannadasan, it's passed more than 10 days from previuos reply; may I have some updates on this basic functionality? We have multiple boards and this beaviour affects all of them.

Hi @Kothandaraman Kannadasan any news on this? Best regards

I also add that there are a lot of failed services on a freshly fladhed board (tried 3 times with FHD and 4K images, same result). It seems that the image you are providing has some issues. $ syst...

@Kothandaraman Kannadasan Thank you for your reply, all the permissions are fine, i tested also other services like the official docker's one. Same result. Service started if launched with systemc...

I’m facing an issue with a systemd service I created on an I-PI SMARC RB5. The service is supposed to execute a simple Bash script at boot, but it does not start automatically. I tested variu...

Quick update, I solved the issue erasing the partitions and flashing again.

I am working with a I-PI SMARC RB5 board that I have recently flashed with the latest versions: LEC-RB5-8G-4K-UBUNTU_20_04-HLOS_2v1.0.2_23_08_07  LEC-RB5-8G-FHD-UBUNTU_20_04-HLOS_2v1.0.2_...

@moto x3m  The Schematic of the I-Pi SMARC IMX8M Plus outlines the detailed design and functional layout of this versatile embedded system-on-module. 

@Riccardo Damiani,S_GPIO ->  GPIO from the SoC Lines.E_GPIO -> GPIO from the SX150Q(i2c GPIO expander). (CN1001)Header - 1 has UART(TTL) Pins [6(GND), 8(TX), 10(RX)] To manage the GPIO...

Also, the two free serials SER1 (/dev/HS1) and SER2 (/dev/HS2) seems to be RS232 serials. Is there a TTL UART serial that I can use? For example pin 8/10 of the expansion header 1 of the board?

Thank you for the reply.  What is the difference between E_GPIO and S_GPIO and is it possible to change the logic level of the GPIOs? For example pin40 seems to be 3.3V while pin7 seems to be...

Hi Martin,  please ensure there is good airflow over the passive heatsink, if not you can connect a fan to the fan header on the side of the boad. It should not lock up, but throttle, did yo...

Hi, we have an I-PI SMARC Elkart Lake Atom board, we are seeing temps of 60 degrees plus while in the BIOS, once the OS has booted (Windows 10) with nothing running we see temperatures rising to 90...

Dear @Riccardo Damiani, As you requested, we have updated our documents. Please refer to the links below.https://www.ipi.wiki/pages/rb5-docs?page=GPIOUtility.html#GPIOUtility.html https://www.ipi....
