For one of my client I have to update u-boot from 2017.1 to 2019.1, compilation is fine but I don't any output on the UART anymore,
Any advice to debug u-boot UART? There were probably many changes in 2 years... :(
For info It's a custom board based on Zynq7000 and I use Xilinx SDK 2017.4 to flash trought JTAG.

Are your getting any fsbl logs. if so please share that logs.
Note: Please make sure vivado & petalinux should be same version. It should not use both diffrent versions.
Thanks & regards

how did you migrate, did you just get the 2019.2 brach of u-boot and build? Can you share the the defconfig?

You are right, my post need to be clearer.
For security reason I have to update u-boot from 2017.1 to 2019.1.
@aravindb I don't use petalinux, I made all with meta-xilinx and Yocto (zeus branch)
@stephenm for a first step I using picozed-defconfig file
No error during Nand flash process.
Do you think I have to change something inside the device-tree(dts) ?
