Since the ACP port does not work for your application and using CMA without ACP makes no sense, I think the solution for you is to not use CMA and go back to the previous solution by limiting the memory available for Linux via device tree.
This can be done by adding the following lines to the first section of dts/common.dts:
Code: Select all
memory@0 {
reg = <0x0 0x10000000>;
};

Hi Pavel,
Could you please describe how port selection is made in axi_hub.v?
Namely, for example. when interface 0 in axi_hub is addressed, how does it selects between b00_bram and s00_axis/m00_axis?

It does not really select between b00_bram and s00_axis/m00_axis. Normally, b00_bram and s00_axis/m00_axis are not used simultaneously. The selection is therefore carried out by the developer during the process of interconnecting blocks and interfaces.
If a BRAM is connected to b00_bram and at the same time a FIFO is connected to m00_axis, then data will be written to both the BRAM and the FIFO.
For reading, s00_axis has priority over b00_bram. So b00_bram is read only when s00_axis_tvalid is low.

Hi Pavel,
I tried merging and compiling the latest SD card image, but I run into errors related to realtek driver:
Code: Select all

Do you happen to have any insight how to rectify these errors?

It looks like you are using a newer version of the Linux kernel and an older version of the rtl8188eu driver. Try to do a complete rebuild:

Thank you again Pavel.
By the way, after some poking around, I was able to resolve the issue with the image script that I have mentioned few months ago in this thread. I ended up adding a --partscan option to losetup command on line 15 of your image.sh script.

Hi Pavel,
I wonder if it would be possible to utilize recent Red Pitaya EEPROM calibration utility with red pitaya notes debian image? I recall that you used to maintain debian-ecosystem script in the years past which provided some of the vendor functionality, but I guess the development branches diverged too far by now?
