Re: About default program signal flow of the AD1701 ,why not output?
Sorry to hear you're still not passing sound. As you know, it's always hard to troubleshoot a prototype where both the hardware and software are unproven. It's also hard to troubleshoot...

Thanks. The AD9361/4 use the same HDL code, however that might make trouble to optimize the HDL code size into the FPGA.We want to use 1T/1R AD9364 instead of applying the current AD9361 HDL code which...

Re: AD9361 BBPLL fails to lock on prototype
Works fine on the evaluation board with the 40MHz reference?Take a look at the ad9361_setup() function.That should be the same - 80MHz uses the clock divider - so it will be again 40MHz.You could try...

View ArticleRe: Use of VDMA in DAC reference designs
Hi DragosB, I don't know what the limit is actually. My trial and error show that when tx_count is 78 or more, the main.c will run till dac_dma_setup(fmcSel) and then the processor stops responding....
View ArticleRe: Transmitting arbitrary signal from file in No-Os reference design.
Thanks rejeesh! It seems to me, there is a magic maximum length of tx_count being 78, beyond which the processor will stop responding in loop.I don't know why. Is it more likely my misunderstanding in...
View ArticleRe: how to convert hdmi 1080p60 to dvi 1080p30 8bit?
You will need a frame buffer to store the 1080p60 video. You can then throw away every other frame on the read side by manipulating frame pointers and output 1080p30. Its that simple. This frame rate...

When I probe DAC_FRAME_P/DAC_FRAME_N (H16/H17 of FMC connector) on scope, it is Lo/Hi. It seems that after the sets up, the no-OS deafults DAC_FRAME_P low. Yes, SED of "dac_test(fmcSel)" ran...
View ArticleRe: AD9122 FIFO
No - I meant- will you please try setting it yourself and read those registers again?It should only get asserted (high) for one clock cycle during start up - and stay deasserted (low) afterwards.
View ArticleRe: AD8310 offset problem
No, I think you are correct. That will just increase the RC time constant of the discharge of the coupling caps and thus the tail that is seen on the output. If you really want to solve the problem,...

Re: Transmitting arbitrary signal from file in No-Os reference design.
That doesn't mean your code is incorrect. It may be due to some other reason.Which board are you using? Try a simple loop (with any data) on the same board.Add a print statement and see which location...
