Hi all ~I'm using ProFTP and try to use ftpasswd perl script to manage AuthUserFiles. But when I run ftpasswd command on my system I get the following error Can't locate Fcntl.pm in @INC (you may need to install the Fcntl module) (@INC contains: ...
I'm trying to get PWM running on an STM32MP157-DK1.When i run the example code "TIM_DMABurst" there is a PWM (had oscilloscope on Pin). Then I configured TIM1 on Channel 1 and the DMA on Stream2 with CubeMX. The generated code looks exactly the same ...
we are developing the application by using STM32MP1 processor in bare metal.we are able to wake up Cortex A7-1 from Cortex A7-0 both are working fine. Now we tried to wake up Cortex M4 from Cortex A7-0,But we are unable to wakeup Cortex M4 from Corte...
I have custom board based on STM32MP153C.This board has 7 serial ports. I configuring these ports with STM32MP1Cube.After linux boot 4 of these serial ports become disabled Driver doesn't probe them and they are in "disabled" state in /sys/firmware/d...
we are working on STM32MP1 in UBOOT 2018 version .we are trying to access the EMMC from UBOOT by using following commands in the below linkhttps://develop.phytec.com/phycore-imx7/linux/pd18.1.0/how-to-guides/flashing-and-booting-from-emmcEMMC is de...
Hi,For SD, we just take the card to PC, write image directly, take about few minutes for 4GBFor EMMC, we have to use STM32CubeProgram and this take so long, up to an hourI am using USB, not serial. For Serial, it could be a day for 115200bps.We are n...
