there is bug in u-boot 0106-MIPS-add-board-support-for-Gigaset-SX76X config file:
+#define CONFIG_ENV_OFFSET (256 * 1024)
and it should be:
+#define CONFIG_ENV_OFFSET (192 * 1024)
since kernel is positioned at 0xB0040000:
+#define CONFIG_EXTRA_ENV_SETTINGS \
- CONFIG_ENV_LANTIQ_DEFAULTS \
- CONFIG_ENV_UPDATE_UBOOT_NOR \
this bug causes overwrite of image file positioned at 0xB0040000 with Environment configuration that should be stored at 0xB0030000.
WLan does not work, cause could be that wlan eeprom configuration is not loaded, some patch previously positioned eeprom at 0xb07f0000, as defined at:
Paragraph: Installation procedure for Barrier Breaker (BB), point 8.
