@文心快码ttys5 - failed to request dma, use interrupt mode 文心快码 ttys5设备在请求DMA时失败,将使用中断模式。 在Linux系统中,串口设备(如ttys5)通常可以通过DMA(直接内存访问)或中断模式进行数据传输。当系统尝试通过DMA模式进行数据传输但失败时,它会回退到中断模式。这种情况可能由多种原因引起,包括DMA控制...
DMAMUX adds a fully configurable routing of any DMA request from a given peripheral in DMA mode to any DMA channel of the DMA controllers. DMAMUX does not add any clock cycle between the DMA request sent by the peripheral and the DMA request received by the configured DMA channel. It ...
It offers fully configurable routing of any DMA request from a given peripheral to any DMA controller and/or controller DMA channel. This document explains the various DMAMUX features of the products listed in the table below, how to configure the DMAMUX, and provides guidance on the use of ...

Solved: Hi, There are some interrupts in my project, one is DMA int, others are Timer and GPIO int, MCU can enter either of interrupt service
By setting them to a high value in the Top Design, I can then use SPI_xx_DMA_SetXloopDataCount as I need. However, I'm now unable to trigger the DMA interrupts. I also added an SPI_DONE interrupt, but that doesn't get triggered as well. I tried changing the interrupt of th...

Step 3: Inside CMSIS V2, go to Advanced settings and set USE_NEWLIB_REENTRANT = Enabled. Leave everything else as default. Step 4: Go to LWIP and enable it. Set LWIP_DHCP = disabled in General Settings and then write in the fixed IP address. In ...
Drivers often use the value of lbolt before and after an I/O request to measure the amount of time it took the device to process the request. The drv_hztousec() function can be used by the driver to convert the reading from clock ticks to a known unit of time. Return Values The ...
