Actually you should enable the option in configs/sandbox_defconfig, not lib/Kconfig. See the condition used by compression.c: obj-$(CONFIG_SANDBOX) += compression.o Also, for me the test fails: ./b/sandbox/u-boot -c "ut_compression" ... testing lz4 ... orig_size:350 compressed_size:276 uncompressed_size:350 compress does not overrun Failed: ret != 0 lz4: FAILED ut_compression FAILED Regards, Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
