How can the addresses be setup with the eDMA module ? Can you please explain ? Thanks, Manu 0 Kudos Reply 10-19-2020 12:00 AM 5,651 Views jeremyzhou NXP Employee Hi,Thanks for your reply.Let me explain how to implement the workaround of ERR011164.As the below diagram sh...
1.When using the S32K312 FLEXIO SPI DMA feature, the CS pin exhibits a waveform with a duty cycle of approximately 43.42%, as shown in the diagram below. 2.Help to explain the reason for the 43.42% duty cycle waveform appearing on the above-mentioned CS pin, the source code is ...
Can you explain the differences? I'm wondering if having multiple Refs is really valuable for us. You can read the buffer while it's also being read by the DMA in parallel. Not that I can give you an example about why that's useful off the top of my head. But it's a memory saf...
(move data from on-chip memory to system memory), or simultaneous read and write. The user can also control the transfer size of each descriptor, the number of descriptors, and how many loops the DMA runs. There is description to explain all the options when the application is started. ...
This article focuses only on DMA mode for RX operation and explain how to handle unknown data length Every STM32 has at least one (1) UART IP and at least one (1) DMA controller available in its DNA. This is all we need for successful data transmission. Application uses default features...
You can see that bus mastering is enabled with the VGA controller as we enable bus mastering before we have the GPU do DMA functionality. However, the “Xilinx Corporation Device” is still the same as we don’t modify it. Could you explain more on how the Xilinx...
If the system does not pick this up, I am guessing from the component ptf , then I think it will go into a single cycle mode, which would explain my SDRAM numbers. Comments anyone? Thanks Translate 0 Kudos Copy link Reply All forum topics Previous topic Next topic ...
