New Product Ideas / Re: ZX-Spectrum clone

Last post by talharizwaan - April 12, 2025, 02:44:52 PM

That's a cool idea, Darie! An Xberry Pi or Spectrum 128 clone would be a fun project, especially for retro computing fans. I'd love to see a modern twist with HDMI output and SD card support. Have you started building or just exploring the concept for now?

STMP1 / stm32mp1 tty mapping

Last post by edmondog - April 12, 2025, 11:01:25 AM

Good morning.
I have an stm32mp1 lime board connected to a lime overlay. It works just fine and I can easily control a MOD-IO2 board, but I can't find what tty devices map the uart/usart on uext1 and uext2 connector on the overlay.
Regards.
Edo

New Products release / Re: PICO2-XXL with RP2350 and ...

Last post by ardavast - April 12, 2025, 06:15:11 AM

Hello, I received a rev B, but only schematics for rev A are available.  After poking around with a multimeter I found that in this revision the SD card MISO has been moved from GPIO12 (EXT1-32) to GPIO24 (EXT1-23).  Please upload the rev B files.

I also want to ask you to upload the circuitpython that comes with the board, cause I flashed a different firmware, and only after that I found out that there is no way to download the original firmware with which the board came.

It is probably a software issue, maybe take a look here:

https://github.com/nxp-imx-support/meta-imx8mp-isp-imx219

Maybe search for other people that have used IMX219 with IMX8MP.

I believe the support for STM32wlx chips was added in OpenOCD 1.11.0, so it is expected to have problems with OpenOCD 1.10.0.

NXP / Connecting RPi Camera to IMX8M...

Last post by visitor8 - April 09, 2025, 04:39:36 PM

I am attempting to connect a raspberry pi camera (IMX219) to the MIPI CSI port. I have the proper cable to convert the 22 to 15 pin and I tested the power to make sure everything was routed properly. I am also running the default buildroot. When I connect the camera to either CSI port and run i2cdetect, I am not noticing any new address appear. Has anybody had a similar issue or success?

I tried using the openOCD.exe which comes with STM32CubeIDE 1.10.0. This version just issues a message and does nothing:

Two Remarks:

1. Launching the debugger fails with a probability of about 50%.

2. OpenOCD.exe which came with STM32CubeIDE 1.10.0 does not work:

C:\ST\STM32CubeIDE_1.10.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.openocd.win32_2.2.100.202206011703\tools\bin\openocd.exe -f interface/cmsis-dap.cfg -c "cmsis-dap vid_pid 0x15ba 0x0044" -c "transport select swd" -c "adapter speed 2000" -f "target/stm32wlx.cfg"

ESP32 / Re: ESP32-POE-WROVER

Last post by LubOlimex - April 09, 2025, 08:12:12 AM

Nice. You just need to change the pin for the Ethernet clock. In boards with WROVER module it is GPIO0 (instead of GPIO17 that is used in ESP32-POE that is with WROOM module). In the code above it looks like this:

- In boards with WROVER module:

#define ETH_CLK_MODE  ETH_CLOCK_GPIO0_OUT

In regular ESP32-POE (WROOM module):

#define ETH_CLK_MODE  ETH_CLOCK_GPIO17_OUT

Thanks, I was able to get the Arduino example running. Will do some more digging to figure out how the clock is getting enabled ...
