Resolved! problems with installing fftw package

Hi! Have some problems with installing fftw package. I tried to install it to st-image-weston and st-example-image-xfce, but received same error when bitbake run do_rootfs. Can anybody explain this problem?Build Configuration:BB_VERSION = "1...

Resolved! Why the WXGA (1366x768) at 60fps limitation for STM32MP157C MPUs?

I am evaluating different dual-core ARM Cortex-A7 MPUs for their graphical features; one of my requirements is that I need to support a 1280x1024 TFT LCD at 50-60fps using 16 or 24-bit parallel RGB interface.The evaluation kits offer small LCDs below...

Resolved! Hello. We are trying to reset MCU from within MCU by asserting SYSRESETREQ it in Cortex M4 AIRCR register (by calling NVIC_SystemReset). After that the MCU halts and FW is not running.

If we emulate the MCU watchdog reset on STM32MP1 it works fine. MCU is got restarted and runs after that. SYSRESETREQ assertion (by calling NVIC_SystemReset) works fine with dedicated M4 processor.We wander what can be a problem on STM32MP1 ?

Resolved! What is the maximum transmission interprocessor bandwidth on STM32MP1?

I am interested in the maximum transmission bandwidth between the A7 core and M4 core on the STM32MP1.I did some test using RPMsg framewirk and sent messages with length 496 Byte from the A7 core to the M4 core. Therefore I modified the OpenAMP_raw e...

Why does Linux Kernel not apply ST-sensor driver to pressure sensor?

I connected an external sensor via i2c and modified the device tree dk2 with following addition:&i2c5 { status = "okay"; clock-frequency = <100000>; pinctrl-names = "default", "sleep"; pinctrl-0 = <&i2c5_pins_a>; pinctrl-1 = <&i2c5_pins_sleep_a>...
