Since the PIN of STSPIN32F0 is not enough, it is implemented to view log messages using PA14 (SWD_CLK) as UART.But after that, I can't download it, so please inquire.1. Could you explain that re-download the MCU in this state?2. I don't have any PI...
Hi.It seems, that sometimes data in cached memory is corrupted.DMA transfer data from SPI to SRAM2 (0x30000000). I use ping-pong buffer in SRAM2 (two similar buffers). Data processing performing for first part of the buffer in thread, while second it...
Hello, I tried to start QSPI working on a Single flash mode but have a problem with non readable part config registers (NonVolatile, Volatile and Enhanced Volatile). As I understand when working in Dual Flash mode this registers should write and read...
e.g: Below are the execution time of memset() function at different locations.1. memset() plcaed at 0x0000000000219e96 : Time = 57.10 usec for 3k buffer size.2. memset() placed at 0x0000000000219d42 : Time = 28.66 usec for 3k buffer size.- memset is ...
Hello,I am using the ADC1 + DMA to sample 10 analog channels on the CM4 without any MPU config. When I remove any external trigger e.g. 3.3V power source on the analog channel, and I start sampling all 10 channels via the DMA , all values inside the...
Hi,I am trying to use the ADC with DMA but the values on the buffer are not being updated. Next i detail the steps that i have done:Disabled the ICache and DCache.Place the DMA buffer in a separate section in RAM_D2 with the address 0x30000000, so th...
The execution of an interrupt handler can be preempted by an exception having higher priority.How many interrupt by an exception having higher priority can be executed?In the link below, two interrupts are generated. Is this number infinite?
