I'm trying to install the distribution package but I'm at the point of the proxy issues and I don't know what to do. sudo apt-get update sudo apt-get install corkscrew git config --replace-all --global core.gitproxy "$HOME/bin/git-proxy.sh" git con...
Hello,I am developing on the STM32MP131FAE board in a bare-metal environment.This chip does not have internal Flash, so I am planning to load a bin file from external Flash at initial boot.The Flash will store two bootloaders and two main firmware im...
I have a small micro that needs to run before the MP157 is active. The voltage coming gin is 5V, but I need 3.3V. Is there an always-on LDO in the STPMIC1 for such purpose? I assume the internal LDO is not te be used?Do I need to program the voltage ...
Is there a way to build only optee, etc. up to the level of u-boot?It would help to ease board bringup, checking the dts effects, do some basic testing. Regards,Roland
Hi all,I'd like to move the USB HID/CDC function, implemented in the Ux_Host_HID_CDC_ACM sample, from TypeC OTG port to USB host port.Does it make sense?I started to create a usb_host.c based on usb_otg.c, changing the OTG into the USB Port1 referenc...
i am using stm32mp157d-dk1 and i am using virtual box and i want to make a gui using c++which application should i use so that i can access the adc and dac in linux.using arm cotrex a7 can i access/control the adc and dac. for example when I click a ...
I'm buildning my own computer by using STM32MP151AAC3.I'm going to draw lines for the HDMI connector. I have one question: Can I transfer sound via the HDMI cable? For example if I run OpenSTLinux onto the STM32MP151AAC3 processor, and then I connect...
Hi all,I'm writing a USB composite device support (baremetal) for MP135: it must support a custom interface and a CDC profile. Now I'm testing the CDC side connecting the USB cable with a PC: Windows mounts correctly a virtual serial port and I open ...
Hi,I am working on STM32MP133FAFx (I2C Master) for I2C communication with STPMIC1 IC (I2C slave) fast mode(400KHz) and HSI clock(64MHz). I2C->TIMINGR = 0x00C0216CFor writing data TXIS flag is getting send and I am writing the register but when trying...
Hello We are using STM32MP157A processor in our custom board. Now we are implemented IWDG1 in Cortex A7 processor. The IWDG1 bit is not going to set after reset the processor with Watchdog timeout.we checked in following registers• RCC BOOTR...
