I’m having some trouble getting u-boot to boot from eMMC. I’ve evaluated my system using the DK2(using SDCARD) and i’m now porting to a custom board. The custom board contains a STM32MP157CAB and a eMCC connected at sdmmc2.My u-boot devicetree(stm32m...
Hi:When I do not enable sdmmc1 in the device tree , a null pointer error will appear, as follows: Unable to handle kernel NULL pointer dereference at virtual address 00000020[ 4.406546] pgd = b1eff48d[ 4.409244] [00000020] *pgd=00000000[ 4.412826]...
Hi,for our testing i want to activate the fullspeed OTG on the Pins PA11,PA12. VBUS_OTG is not routet out the Chip on the DK2. Is it possbile to use the FS phy on PA11/PA12 on the DK2 board?Best regards,Niklas
I am using 2 passive tamper detection in my board that is routed to PC1 (TAMP_IN3) and PC13 (TAMP_IN1) and I want to handle both tamper pins events in linux userspace. I have achieved my goal by adding small code at plat_setup and disabling tamper in...
Hello,I'm trying to connect some sensors to the I2C1 connectors of the STM32MP157A-DK1 and read datas from a linux application (Cortex A7). It doesn't works...But I successfully read data from the I2C5 connectors from the Cortex M4 processor.I used t...
Good morning,I'm working on a C++ project to collect data from a peripheral sensor using the STM32MP157C-DK2.The estimated amount of data is at least 100 MB, so I have to use the DDR3 to store these data and then trasmit them over Ethernet using at t...
In our early evaluation phase, the stm32mp157 chip is ideal for our requirements - with the ability to do hard real-time processing with the M4 core but still have a Linux framework to develop interfaces to upstream processing applications. We feel ...
I'm trying to get TIM7 interrupts working with the STM32MP157C-DK2 kit. I've added the necessary configuration to the DTS file:&m4_timers7 { pinctrl-names = "rproc_default"; pinctrl-0 = <&timer7_pins>; status = "okay"; };Do I need to enable the i...
Hi,I flashed OS "en.FLASH-stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12.tar.xz" to board STM32MP157C-DK2. Then remove all the cable,and only remain a type C cable connected with my laptop Type C port.But the kit can't power on.Could you tell me how t...
