EC20 Linux¶
Kernel Version¶
It is using a modified version of a Qualcomm_Kernel which is available from https://source.codeaurora.org/quic/femto/kernel/msm
$ for rev in `git tag | grep \^LNX.LE.2`; do patchsize=$(git diff -w $rev | wc -l); echo $patchsize $rev; done 19247 LNX.LE.2.0-23056-9x15 19188 LNX.LE.2.0-23060-9x15 19188 LNX.LE.2.0-23061-9x15 127972 LNX.LE.2.0-23115-9x15
based on this we can see that the EC20 is using a LNX.LE.2.0-23060-9x15
derived version with about 19k lines of residual diff of Quectel specific changes.
