Our self-made board contains emmc and lpddr3 (1GB, 32bit). The error message when downloading the image is as the attachment. Use Uart to monitor during the download process to get the following information:NOTICE: CPU: STM32MP157AAC Rev.Z NOTICE: Mo...
I have a generic parallel LCD screen. 24 bits RGB, vsync, hsync, pclk, data_enable, disp_on,..The examples I see on the wiki only shows the HDMI connection and DSI. How do you configure this for DPI?Is this a good start? (In the device tree)panel_bac...
we using raspberry pi 4 to run Apache python , mysql an c kernal and it runs excellent om 4 Giga ram.we would like to move to stm32p1 , can it being compare and be replaceable ?
Hi all,i am trying to interface es8388 to I2S3 bus,Here are fragments from device tree : sound { compatible = "audio-graph-card"; label = "STM32MP1-SOM"; routing = "Playbac...
I want to use the M4 kernel to display some animations and images that can be rendered on the GPU？
We are using rauc to perform remote updates on your target devices.However, to create the rauc bundle, rauc uses a different image format than the ST image created.The default imagesource in rauc is:imgsource = "%s-%s.%s" % (d.getVar('RAUC_SLOT_%s' %...
I have a new STM32MP157C-DK2, it stops (hangs) very often.Especially when I run a demo.The 3D GPU demo runs no longer than 30 seconds.The Video playback doesn't finish mostly and then the system crashes again.Is this a known problem. Are there update...
I'm currently working with the Seed STM32MP1 SoM which has STPMIC1 attached to I2C2. I've been working on setting up a device tree for it, but I've been hitting some bugs. When booting the mainline ATF with my device tree (modified DK2 board, just wi...
Hi,I'm trying to have some accurate perf measurements with the STM32MP1 for my program on Linux. I've tried several things, among them to use perf Linux tool.The number of cycles does not match the time elapsed, i.e. the freq processor is at 650Mhz a...
