So U-Boot reads/writes from Address 0x21900000 within the user-area of eMMC.

What may have trashed the partition ? Maybe the blockaddress of 0x21900000 (1099776 dec) is within the partition where zImage/dtb is stored. Please double-check the CONFIG_ENV_OFFSET address. best regards, hannes _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
