How to set autoboot in PetaLinux image

[herogian]

Hello, I built a Linux image with the Petalinux tool, with the following u-boot parameters:

console=ttyPS0,115200 earlyprintk uio_pdrv_genirq.of_id=generic-uio clk_ignore_unused root=/dev/mmcblk0p2 rw rootwait sdhci.debug_quirks=64 cpuidle.off=1

the "problem" is that every time I would like to boot the linux image I need to connect to the serial port and type "bootm" as in figure:

there is some parameter to configure the autoboot?

thanks

Yes, you can set the "bootcmd" variable (note, you also need "bootdelay", but you likely already have that). Reference: https://www.denx.de/wiki/DULG/UBootEnvVariables

Ok thank you, it's possible to set these parameters permanently, without re-generating the petalinux image?

Usually you can use "saveenv" command to save these parameters permanenty.

This relies on u-boot having been configured to store the parameters somewhere (such as QSPI flash, EEPROM, etc).
