buratino Posted October 13, 2020 Posted October 13, 2020 Hello! I wrote the wrong bootloader to the emms, now the download does not happen with either emmc or micro-sd. U-Boot TPL 2020.10-00676-g9885313b9a (Oct 13 2020 - 06:24:16) sdram_init: LPDDR3 - 933MHz failed! rk3399_dmc_init DRAM init failed -22 Missing DTB Now I can't use the board in any way, how can I clear the emmc memory?
