Hello,
I was able to test this series on the imx93-phyboard-segin. Up to that specific commit no issue to report. That specific commit however, using an updated dts subtree at 2639a0e2fd, fails to boot. There is no more garbage on the UART, but the boot stops after BL31 is started: U-Boot SPL 2024.04-rc5-00388-gf81e4e85fd6-dirty (Apr 14 2024 - 12:15:51 +0200) SOC: 0xa0009300 LC: 0x40040 M33 prepare ok Normal Boot WDT: Started wdog@42490000 with servicing every 1000ms (40s timeout) Trying to boot from BOOTROM Boot Stage: Primary boot image offset 0x8000, pagesize 0x200, ivt offset 0x0 Load image from 0x45c00 by ROM_API NOTICE: BL31: v2.8(release):lf-6.1.36-2.1.0-0-g1a3beeab6-dirty NOTICE: BL31: Built : 11:39:38, Aug 7 2023 Not sure where that could come from.
