Hi!I noticed this.The FC-135 32.768 kHz crystall with CL = 12.5 pF, ESR max = 70 kOhm and C0 = 1.0 pF is suitable for MP1 products.The gmcrit is 2.1631 uA/V.When I do the math, i found out that gain margin is below 5.C0 = 1.0*10^-12;CL = 12.5*10^-12;...
Hi there, I'm trying to configure a CubeMX project, starting from scratch, for a custom board based on a STM32MP153CAC3. And I'm having an issue with the MPU clock setting. In particular, I can't select any MPU Clock Mux option and see the PLL1 tree ...
Hello, I'm planning to create a new board using the STM32MP157FAC.I've referenced the circuit diagrams of both the Discovery board and the development board to design the PCB and assemble the components.I've successfully connected the power chip, STP...
Hi!I was recommended to use the pre-built basic start-up projects for the STM32MP series, instead of buildning my own from scratch.Solved: Re: Why are the DDR_DQ signals mixed in unsorted o... - STMicroelectronics CommunityThe project files are Altiu...
I am trying to build a custom board for the stm32mp151A using the STM32MP15 Evaluation boards as a reference.U-BOOT starts, but the kernel won't start, and I'm at my wit's end.1. When the device starts up, the console displays "CPU: STM32MP151AAC Rev...
1.) HAL_Delay(x) hangs forever when restarting CM4 using Hardware Timer for Systick. Every unit was forced with RESET/RELEASE. Any firmware change could not solve it. Have to repower the board. Happens in Normal and Engineering mode!2.) HAL_Init() ha...
Hello,I follow this guide X-LINUX-AWS Expansion Package cmd) aws iot attach-policy --policy-name ${TOKEN_EXCHANGE_ROLE_ALIAS_POLICY} --target ${CERT_ARN}but, error occurred (ResourceNotFoundException) when calling the AttachPolicy operation: Policy n...
Hi, I am trying to create an image for writing to NAND memory.The problem is that when generating a TSV file using Yocto, I get a layout without a bootfs partition.In this case, it is unclear how to load the Linux kernel and the DeviceTree.Can someon...
Dear Community,we currently try to set up a Murata LBEE5KL1YN with an Ocatavo System OSD32MP157c. We use ecosystem5 and kernel 6.1.28. The problem is, the brcmfmac driver is not loaded. We do not see any output of brcm in the boot log and also not i...
Looking at AN5478 implies that the entire line of STM32MP13x has a DCMIPP interface. However for STM32MP131 DCMIPP is not mentioned in the datasheet.Does the STM32MP131 have a DCMIPP interface? If so, are the pins and the functionality matching that ...
