Hi,Is there a way to program STM32U585 MCU via USART1 peripheral using Embedded Linux processor? Except BOOT0 pin and RESET pin of U5 MCU what else need to be done to get into Serial Programming mode? Thanks in advance,Nenad
Hi,I'm interested in hardware connection of STM32U5 and Smart card. They can be connected directly or there need to be Smartcard Interface circuit between (like ST8024)?Thanks in advance,Nenad
Hi,I'm interested how to change CPU frequency from 650MHz to lower frequency. I looked those two links:https://wiki.st.com/stm32mpu/wiki/How_to_change_the_CPU_frequencyhttps://wiki.st.com/stm32mpu/wiki/Clock_device_tree_configuration_-_Bootloader_spe...
Is there a way to increase code size which is used on M4 MCU? I saw some memory regions in device tree, but it is not clear how to do a change. Any info will be appreciated.Best regards,Nenad
Ok, so do we need to do something in hardware or software to set usage of LDO only? Can we leave VLXSMPS and V11 pins unconnected? On ST evaluation board B-U585I-IOT02A they connected those pins as shown in the picture in attachment. Thanks in advanc...
We measured overall current consumption of our board. There was no difference in current draw (at the same voltage off course), when we watch boot sequence of 650MHz and 400MHz STM32MP1 (VDDCORE = 1.2V). So I tried to lower down VDDCORE to 1V. I modi...
I fixed pll1 node and now it looks like this:pll1: st,pll@0 { compatible = "st,stm32mp1-pll"; reg = <0>; cfg = < 3 49 0 0 0 PQR(1,0,0) >; frac = < 0x000 >;};So now I have cpu frequency of 400MHz. I also edited opp nodes in tf-a and Linux device ...
After long examination and trying, we figured out that reason for this behavior was using HAL_RTC_GetTime and HAL_RTC_GetDate on Cortex M4 when A7 was in low power mode. I read somewhere that HAL RTC driver is not ready for use, but we managed to get...
