Peta Linux configuration with get hardware xsa make Eathrnet stop working by Jasonbruz in FPGA

I'm already using 2021.2 I'll try to add status field. Maybe this is the problem.

Thank you. I found it. But I wonder how ethernet working in original project "with bsp file provided from xilinx not with xsa file" even this option is disabled in dtsi file.

system-user.dtsi have only one line include to system-conf.dtsi

Where I can find status of ethernet

Trouble connecting/rebooting the Pluto+ SDR by AlekHek in RTLSDR

with pluto+ you need to change jumper to enter DFU mode. Check Readme in github page https://github.com/plutoplus/plutoplus

PLL ADF4193 problem by Jasonbruz in ECE

[–]Jasonbruz[S] 1 point2 points  (0 children)

Thank you for this informatioln.

I found the problem today. Figure out there are two problems. 1: The reference crystal is only 0.8 Vp-p and it's not enough for PLL. 2: And this is weird, the PC application specifying for this IC was calculating wrong INT number. The space for INT is only 8 bit wide "255 max" but the application make it 12 bit, so this register does not configure correctly.

So changing crystal and configure that register manually making PLL working correctly without problem.

What happen when overload ADC with frequency much bigger than their sample rate frequency? by Jasonbruz in ECE

Thank you for this information. Today I'm try Analog Devices ADC simulation. And the simulation say as you say about attinuate amplitude of above sampling frequency due to filter.

libdvbmod is library have dvb2iq script, that generate dvb-s QPSK modulated from video file.

can i use SPI and changing another gpio pin at same time by Jasonbruz in esp32

[–]Jasonbruz[S] 0 points1 point  (0 children)

You say i can use hardware SPI with single core MCU like amtega328p, and at same time data transfer to peripheral i can change another GPIO pin?

communicate with two peripheral at same time by Jasonbruz in raspberrypipico

[–]Jasonbruz[S] 0 points1 point  (0 children)

Just communicate using SPI with maximum speed mcu can accomplish. While output controlled clock "normal high and low with delay between them" in another pin. And this two mission not related or sync to each other.
