My advice is to search and then post in the NXP forums. I see similar error massages in this thread here:

NXP / Programming M core on iMX8MP
Last post by jospuntnl - September 12, 2025, 02:44:13 PM
Hi,

I've been trying to program the M-core of the IMX8MP for a while now, and after messing around with memory adresses, I've finally got a firmware file that does not immediately get rejected. Sadly I've ran into another issue:

[  412.455146] remoteproc remoteproc0: powering up imx-dsp-rproc
[  412.462385] remoteproc remoteproc0: Booting fw image hello_world.elf, size 185848
[  412.585249] remoteproc remoteproc0: can't start rproc imx-dsp-rproc: -110
[  412.585353] remoteproc remoteproc0: Boot failed: -110

Can anyone tell me what's wrong? I'm running the official minimal Debian OS, on the official evaluation board.

Last post by TomH - September 12, 2025, 05:54:15 AM
All,

I just want to get a board that can boot Ubuntu 22.04, 24.04. Fedora .. . with a JTAG connector on it.  I already have an ARM Olimex USB-OCD-USB-H board and I want to use it with this board.

Any recommendation?
I just want to learn OpenOCD. 

Thank you!

As you noticed by default SAM9-L9260 comes prepared with Linux. This Linux image and sources can be found in this this ISO - mount it and explore the contents inside:

https://ftp.olimex.com/Obsolete_images/SAM9-L9260/SAM9-L9260_Rev.D.iso

Notice that SAM9-L9260 is not a personal computer, it will not boot Ubuntu 22.04 from a flash drive.

Yeah you can also use jumper wires at the UEXT to save from soldering. Just change the definitions, look at the schematic for the GPIOs of the ESP32 at the UEXT.

This is where I saw about 1106, one of the pictures on the product page:

New Product Ideas / SAM9-L9260 board / Boot to an ...
Last post by TomH - September 08, 2025, 08:37:16 PM
Hello,
I recenty got an Olimex SAM9_L9260 board.  After connecting to a 5V/3A power supply, connecting to a null modem, Hyperterminal, I got the board to boot and was able to login.

Now my questions are:
1. The box the board came in is empty.  No quick starting quide.  How do I format / boot to an OS on my SD card?  I tried to format a 128 MB SD card using Rufus and put Ubuntu 22.04 on it.  No go.

2.  Is / Are there any jumper(s) I can set so it will boot to SD/MMC card.  I see this in the SAM9_L9260 file:
Is the SD/MMC card supported?
A: The SD/MMC card is fully supported, including detection of card insertion/removal and
write lock

3. I also saw this in the PDF file.  Where is the NANDF_E and DF_E jumpers are located?
A: Make sure that NANDF_E jumper is not connected and DF_E jumer is connected. If the
dataflash has been correctly programmed, the board should start up

4.  I got this from https://www.olimex.com/wiki/SAM9-L9260

git clone -b olimex https://github.com/OLIMEX/at91bootstrap.git

and when I tried to build it using:
 make sam9_l9260_uboot_defconfig

this does not work.

What's the latest instruction?

Hi and thanks for your answer.
I didn't see where you saw the 1106 library, but in the the comments i found someone talking about the U8G2 library, so i tried it.
Apparently the pin im supposed to use are also part of the UEXT, so they are easily wirable.
I tried in that way, and it worked like a charm.
I'll keep digging in my corner, but i wont hesitate to come back here if i face some new obstacles
thanks for your help

UEXT / Re: MOD-BME280 SPI
Last post by LubOlimex - September 08, 2025, 02:43:31 PM
Only 3-wire SPI is possible since SDO is either connected to VDDIO or to GND. Using CSB, SDI, SDC 3-wire SPI is possible, refer to the schematic:

https://github.com/OLIMEX/MOD-BME280/blob/master/HARDWARE/MOD-BME280-Rev.B/MOD-BME280_RevB.pdf

And also the datasheet of BME280, page 38, table 35:

In the end I moved to A13-OLinuXino-bullseye-minimal-20250305-103314 image and was able to achieve what I needed.

Many thanks for your help. As soon as possible, I will try your solution and update the topic

Looks good so far. Just you tried a library that is made for another controller? From the Amazon page it seems like the display uses SSD1106 (not SSD1306). Maybe try another library or another demo for SSD1106. Also it is possible that the manufacturer used another controller.

Pins 32 and 33 are fine, just make sure that in your code they are defined for I2C operation.

This is usually done with:

Wire.begin (32, 33);

Best regards,
