Just tried booting on a imx8mn ddr4 evk and such a problem does not happen: U-Boot SPL 2022.07-rc4-00007-g57bd363de7 (Jun 10 2022 - 09:42:49 -0300) SEC0: RNG instantiated Normal Boot WDT: Started watchdog@30280000 with servicing (60s timeout) Trying to boot from BOOTROM image offset 0x8000, pagesize 0x200, ivt offset 0x0 NOTICE: BL31: v2.7(release):v2.7.0 NOTICE: BL31: Built : 09:42:28, Jun 10 2022 U-Boot 2022.07-rc4-00007-g57bd363de7 (Jun 10 2022 - 09:42:49 -0300) CPU: Freescale i.MX8MNano Quad rev1.0 at 1200 MHz Reset cause: POR Model: NXP i.MX8MNano DDR4 EVK board DRAM: 2 GiB Core: 139 devices, 22 uclasses, devicetree: separate WDT: Started watchdog@30280000 with servicing (60s timeout) MMC: FSL_SDHC: 1, FSL_SDHC: 2 Loading Environment from MMC...

Not sure why this happens on the imx8mn ddr3 evk and on the kontron_sl_imx8mm though. None of the boards I have physical access show the problem. The Kontron board have remote access only, so not very easy to run git bisect. Are you able to bisect it with the kontron_sl_imx8mm board?
