+++++Content of linked page 'Warning - bad CRC, using default environment'| **Question:** \\
+\\
+I have ported U-Boot to a custom board. It seems to boot OK, but it prints: \\
+''Warning - bad CRC, using default environment'' \\
+Why? \\
+\\
+**Answer:** \\
+\\
+Most probably everything is OK. The message is printed because the flash sector or ERPROM containing the environment variables has never been initialized yet. The message will go away as soon as you save the envrionment variables using the ''saveenv'' command. ++++
