'no serial driver found' after fresh build

Hi, I built a fresh petalinux image targeting the ZC706/FMComms3-EBZ and when I boot the SD card, I get the following at the terminal:
'No serial driver found resetting ...'
I have also experienced this exact issue. Hoping to hear of some resolution for this soon.
Hi guys,
I will have to try this project to see if i get the some. Unfortunately I don't have the time to do it right now. I will give some feedback as soon as I can try this.
we have the same problem with FMCOMMS2-ZC702
I had this issue on ADRV9361 and I was able to resolve it by changing file contents of system-user.dtsi with: ( info found from https://ez.analog.com/linux-device-drivers/linux-software-drivers/f/q-a/118733/fmcomms2-zc702-petalinux-no-serial-driver-found )
/include/ "system-conf.dtsi" / { aliases { serial0 = &uart1; ethernet0 = &gem0; spi0 = &qspi; }; chosen { bootargs = "console=ttyPS0,115200 earlyprintk"; stdout-path = "serial0:115200ns"; }; };
So, I could confirm this problem when bringing support for petalinux 2019_r1. This happened for me with zc706/fmcomms2. The problem seems to be with stdout-path. Setting it to serial0:115200n8 fixed the problem for me. It seems the fsbl or u-boot are somehow relying on this property. It's an odd problem since building things manually, without petalinux, worked out of the box without any change to the device-tree...
However, on the 2019_r1 (petalinux 2018_r3) branch everything worked fine...
The fix for the master branch should come in the next days (hopefully) along with support for petalinux 2019_r1 (which will be the supported release on our master branch).
If someone still has this problem in the 2019_R1 or 2018_R2 branch please let me know...
