Hi, I want to store images in external flash (W25Q32) . I did the linker script modifications. But I couldn't find that what should i do after it. Could you help me?EDIT : I think that I need the external loader.
I just got a stm32L475 Iot Kit.And after compilation, I got this error .st-flash 1.7.0-23-ga9adf9c2021-05-21T22:17:24 INFO common.c: L4xx: 96 KiB SRAM, 1024 KiB flash in at least 2 KiB pages.open(./BUILD/DISCO_L475VG_IOT01A/GCC_ARM/thingsboard-l475vg...
The LPTIMER OF STM32l0(Config BASED ON LSI) can cause the CPU to be temporarily stuck in the LPTIM ISR with no way for the CPU to clear the IRQ.The bug is well described here with a workaround, can someone from ST confirm this issue, and if there is ...
Hi.We have a circuit using an STM32L552RC where we want to measure the VDD rail (3V3) against the external voltage reference. Externally the VBAT pin is connected to the 3V3 rail, the same as VDD. To our understanding, setting the CH18SEL bit of ADC_...
Hi,I'm trying to use SPI to communicate between two boards. On the MASTER side, i am using the HAL_SPI_Transmit(&hspi4, (uint8_t*)TxData,sizeof(TxData),100); and on the slave side i have enabled the interrupt, HAL_SPI_Receive_IT(&hspi4,RxData,1); The...
Hey,I have a discovery board (https://www.st.com/resource/en/data_brief/32f429idiscovery.pdf)This board has an on board 64 MBit SDRAM.Now i have read in other posts that RAM extension is not possible in an SPC line MCU. However what about the STM32F4...
have written this ARM assembly code. It is supposed to put the Fibonacci sequence numbers in R4 register. I'm trying to implement this C code in assembly:int fibbonacci(int n) { if(n == 0) return 0; else if(n == 1) return 1; ...
Hello, I connected my probe StLink V3 MODS via only: GND, SwClk, SwDio (CN2.pin8.13,4) for the beginning. And it rather works. Rather as once I got a strange message instead of debugging. I would like to have my probe reliable so I have found that I...
Dear experts,I'm using Cube to assign pins for my stuff (yep...) and it offers some pins with _C sufix (PC2_C, PC3_C).From the RM0433 fig.75 I gather this is something with the "analog switch" and in order to use these _C pins as AF for some device (...
