I have troubles in setting the polarity of the SPI chip select i/o for an external chip.I noticed In the reference manual that it should be changeable with SPI configuration register 2 (SSIOP bit 28) :Bit 28 SSIOP: SS input/output polarity0: low leve...
I would like to provide power from PI connector. How to avoid error blocking message at the start of the boot that report:************************************************ ERROR USB TYPE-C connection in unattached mode ** Check that USB TYPE-C cabl...
Dear all,We are designing a board using STM32MP1 and STPMIC1 mostly as recommended in datasheet and application note. As we have a wide VIN range we added a discrete DC/DC with a 5V output that supply STPMIC1 VIN.We would like to use STMPIC1 PWR_USB_...
Dear All,We are designing a custom board based on STM32MP1. In some ST documents we can read "if no external battery is used, it is mandatory to connect this pin [VBAT] to VDD." If I check the developpement board schematic VBAT is simply connected to...
The handshake sequence looked a bit odd too. [STMdemo1] (08:07:40): {"state": {"reported": {"Device_Type": "STEVAL-IPD005V1", "Features": [], "Firmware": ""}}}Update request with token "40d4c70c-ec71-4946-9f7b-b6ad2719d965" acceptedI have also tried ...
Hi guys,I'm designing a custom board with STM32MP157C using the MB1263 board as reference.The MB1263 reference design shows the VDD_OTP pin tied to VDD, which is 3V3 for that particular board. My custom board uses VDD = 1V8 instead of 3V3. Should I t...
Good afternoon. I tried to check your example OpanAMP_TTY_echo together with the ssh-t ttyRPMSG0 command after trying to execute the ssh-t ttyRPMSG0 command, the terminal responds Error resolving ttyRPMSG0 port 22 Temporary failure in name resolution...
We would like to build the TF-A image with a different muxer settingfor i2c4. The usual setting is:i2c4_pins_a: i2c4-0 { pins { pinmux = <STM32_PINMUX('Z', 4, AF6)>, /* I2C4_SCL */ <STM32_PINMUX('Z', 5, AF6)>; /* I2C4_SDA */ bias-dis...
