build packetizer_test error

[mhanuel26]

Hello Pavel,

I am trying to build the packetizer_test project using vivado 2016.4 by doing

make NAME=packetizer_test tmp/packetizer_test.xpr

but it fails with following error.

The led_blinker and adc_test build correctly.

I am just noticing this all over

awk: symbol lookup error: awk: undefined symbol: mpfr_z_sub

Could you please let em know what could be wrong?

Thank you in advance,

Thank you for testing the packetizer_test project. Looks like I removed adc_0 from cfg_test with commit https://github.com/pavel-demin/red-pitaya-notes/commit/ce084086a3c677fe09470b62727becf122b708c9 and forgot to add adc_0 directly to packetizer_test.

I've just fixed it with commit https://github.com/pavel-demin/red-pitaya-notes/commit/a32bfd143bebb0f8d7f17fa5963850a8287b6df2.

Thanks, it works now.

Would you allow me a question here. I understand you use the axi_ram_writer for DMA as in adc_test and packetizer_test, in the case of a DAC, what would be the DMA option or how do you achieve high throughput?

Best,

[pavel-demin]

in the case of a DAC, what would be the DMA option or how do you achieve high throughput?

If one of my projects would require the DMA functionality for a DAC, then I think that I'd write a new IP core (axis_ram_reader).

There is also AXI DMA Controller provided by Xilinx.
