cd82f199852d88218e1f17f5ec07cdd9112a89c4 is the first bad commit. When I revert this commit on master I get: U-Boot SPL 2022.10-rc5-00001-gdbcc7add19-dirty (Sep 20 2022 - 00:59:21 +0200) Trying to boot from XIP U-Boot 2022.10-rc5-00001-gdbcc7add19-dirty (Sep 20 2022 - 00:59:21 +0200) Model: STMicroelectronics STM32F746-DISCO board DRAM: 8 MiB stm32fx_rcc_clock rcc@40023800: set_rate not implemented for clock index 4 stm32fx_rcc_clock rcc@40023800: set_rate not implemented for clock index 4 stm32fx_rcc_clock rcc@40023800: set_rate not implemented for clock index 4 Core: 38 devices, 22 uclasses, devicetree: separate Flash: 1 MiB MMC: sdio1@40012c00: 0 Loading Environment from nowhere... OK In: serial Out: serial Err: serial usr button is at LOW LEVEL Net: Warning: ethernet@40028000 (eth0) using random MAC address - 7e:cf:cf:fc:30:4a eth0: ethernet@40028000 Hit SPACE in 3 seconds to stop autoboot. MMC: no card present looks good without the problematic commit. best regards Waldemar
