I think there is another kernel option needed: https://cateee.net/lkddb/web-lkddb/LIBCRC32C.html I'll make the change and kick off the sausage machine. Unfortunately it is set to do a clean build (to avoid a certain class of failures) so the build takes along time to create all the images and sdks, then another few hours to upload. Doing incremental builds locally would save you a lot of time: I think the README here will walk you through the process: https://github.com/balister/sdr-build/tree/rocko-e300 I'll let you know when the upload is done. > > > The output of 'cat /proc/kallsyms | grep crc' command; > > c02cd8d8 t crc32c_cra_init > c0303250 t crc32_generic_shift > c03032d8 T crc32_le_shift > c03032e4 T __crc32c_le_shift > c03032f0 T crc32_le > c0303438 T __crc32c_le > c0303580 T crc32_be > c030a2f0 t crc32_validate > c091364c t crc32c_mod_init > > And I assume that crc32c module is exists?

Um, clearly that isn't an accurate statement. I've seen it done a few times, and Kurt Kiefer published his work which I built on to make these images.
