There seems to be an issue with CubeProgrammer and parsing hex strings that are longer than 8 characters. For example, an offset of 0x05984400 will parse correctly but 0x105984400 will not. It will incorrectly parse as 0x05984400. I am trying to refe...
Hello!I upgraded Linux kernel from 5.4 to 5.15 (ST linux-5.15-stm32mp-r2). Simply added new options to kernel config and kept mostly the same DT. I get the error below in the boot log which renders the whole system unusable.Based on the boot log belo...
In trying to provide X11 support to a Weston distribution, I modified the weston distro conf (meta-st-openstlinux/conf/distro/openstlinux-weston.conf) to read:#DISTRO_FEATURES:remove = " x11 " # with X11 PREFERRED_PROVIDER_virtual/xserver = "${@bb.ut...
I am trying to compile a recipe for STM32MP157c for yocto kirkstone kernel version 5.15 on Soc provided by karo-electronics i.e. QSMP1570 module on qsbase2.I have written a recipe and kernel module for gpio interrupt which is unable to be compile, th...
Suppose I would implement a sysfs interface that enables me to set the dr_mode of the dwc2 driver. Is it possible without huge changes in the code, to change the dr_mode on the fly via userspace? We might use the usb-role-switch functionality of the ...
Hello,I'm using a ST32MP157C-DK2 board to develop an application running on CM4 that basically handles a CAN Standard communication.I routed the FDCAN1 signals on PA11 and PA12 and I am trying to send out some random data with no result...Here is my ...
I want to be able to have the Ethernet port on my board be configured as a link local address and be able to receive DHCP. How can I accomplish this?
I modified the device tree by a patch to disable HW flow control. It seems the port is still working as expected. Why are the pins grouped by 'pins1' ... 'pinsN'? Is this just to apply the same settings to these pins?Why can I remove some pins and RX...
dimensions are the most important thing and the ability to be chassis mountable. the resolution isn't as important but better resolutions wont hurt
How do I change the pin for the u-boot-stm32mp programmer mode at boot up?
