Measured today, and it turned out not to be an eBoot problem at all. I wrote the current-defconfig image (CONFIG_TEXT_BASE=0x3f401000) into NAND from a running U-Boot and power cycled: the BootROM does not start it either. The module drops into the serial downloader, verified by the 0x23454523 UART association pattern echoing back on the console UART. Writing back an image linked at 0x3f408000 through the same procedure, the module cold boots normally. So the eBoot observation from my report was just another face of the same thing: nothing starts an image linked at the bottom of the gfxRAM area, the low 28 KiB are not usable as a load address. It has been this way since commit c0f432c37780 ("configs: vf610: increase maximum size and enforce correct limit") in 2017; the vendor fork never took that change, which is presumably why it went unnoticed. > I would not focus on whatever you are getting pre-programmed on the > board, apart maybe some note in the documentation. Agreed on the standalone flashing. I have sent a two patch series: the first restores 0x3f408000 in colibri_vf_defconfig with the measurements above, the second adds the missing doc/board/toradex page for the Colibri VF50/VF61 with the build, flashing and recovery mode steps. Thanks, Mehmet
