I'm quite confused. The RM0440 states: "Note that read-while-write capability (or RWW) is only supported when the dual-bank architecture is active. This enables programming or erasing one bank while executing code from the other bank." Okay, for me, ...
It is the problem about the dma driver of stm32L452's sdmmc1.ide: cubeideboard: NUCLEO-L452REconfig: sdmmc1 with dma , sd 4bit, without rtossdmmc1 dma config : 1. {sdmmc1 both(rx and tx) : dma2_channel_4} or 2. {(sdmmc1_rx : dma2_channel_4) and (s...
Has anyone tried it and knows that it works/doesn't work?I can guarantee that a DMA request will not occur during the update of these registers.This would be on an STM32G474. I don't have my board as yet, so, can't try it.
The FRAM chip I'm using is cypress.For details, here's a screenshot of my chat with Cypress.Thank you very much.
I am currently experimenting with programming flash memory. I want to figure out how many sectors to erase before writing data into memory. I came across the following snippet uint32_t Flash_Write_Data (uint32_t StartSectorAddress, uint32_t *Data, ui...
I was going through embedded flash programming documentation of STM32F7 . I came across a term called "data read width". can some one explain this term ?Flash memory single bank organization (256 bits read width)Flash memory dual bank organization (1...
For a long time I have been trying to guess how debug components are connected to the Cortex-M7 core in STM32F7 series of microcontrollers. It is supposed to be shown in e.g. the document RM0410 in Figure 587. This figure seems to be a copy of the sa...
The server connects and communicates normally, and the Client experiences a return value = -13, Abort in the connect function.Using the Netconn API, the user program is hercles_3-2-8.exe. PC IP is 192.168.0.223 and Device IP is 192.168.0.222.The code...
There is a misprint in your PM0214 Programming manual "The Cortex M4 processor" in the chapter chapter 2.2.5 "Bit-Banding", above figure 9. Bit-Banding is nicely described there, but of course all bit addresses have to end by "00"... Your first exam...
I have a bug in the I2C bus where sometimes a glitch causes the BUSY flag to be setI found that the only ways to clear it is either by SWRST in I2C->CR1 or by resetting in RCC->ABP1RSTR->I2CxRSTRMy question is, is there any difference I should know a...
