The default zynq-common.h CONFIG_ENV_SIZE is double this value, 128 << 10 == 0x20000. And the default environment is pretty packed (64K might not be enough). If you want your environment to fit within 64K, you will need to reduce the default environment config that is provided by zynq-common.h. > > U-Boot 2016.07-dirty (Feb 14 2017 - 12:59:07 +0100) > > Model: Zynq MicroZED Board > Board: Xilinx Zynq > DRAM: ECC disabled 496 MiB > Error binding driver 'gpio_zynq': -12 > Error binding driver 'serial_zynq': -12 > Error binding driver 'zynq_qspi': -12 > Error binding driver 'zynq_gem': -12 > Error binding driver 'arasan_sdhci': -12 > Error binding driver 'generic_simple_bus': -12 > Some drivers failed to bind > Error binding driver 'generic_simple_bus': -12 > Some drivers failed to bind > initcall sequence 1ef99b98 failed at call 0400ea34 (err=-12) > ### ERROR ### Please RESET the board ### These are all ENOMEM errors, likely caused because they are trying to read/write past the end of the environment.
