I am using the version 17.06.1. I installed the image to eMMC. Then modified the kernel: changed I2C0 QUP driver to GPIO bitbanging and it works as it should. But in addition I lost wifi capability…
if I run
dmesg | grep wcn
the result is the following:
root@linaro-alip:~# dmesg | grep wcn [ 0.205843] irq: no irq domain found for /wcnss-smp2p/slave-kernel ! [ 3.417638] Modules linked in: qcom_wcnss_pil(+) msm_rng(+) rng_core venus_core(+) qcom_camss mdt_loader videobuf2_dma_sg v4l2_mem2mem videobuf2_memops videobuf2_v4l2 qcom_cci videobuf2_core [ 3.749935] a204000.wcnss supply vddcx not found, using dummy regulator [ 3.757107] remoteproc remoteproc1: a204000.wcnss is available [ 3.762295] remoteproc remoteproc1: Direct firmware load for wcnss.mdt failed with error -2 [ 3.768093] remoteproc remoteproc1: powering up a204000.wcnss [ 3.776417] remoteproc remoteproc1: Direct firmware load for wcnss.mdt failed with error -2
Is it happens only for me due to the devicetree/kernelmodule modifications or it happens for everyone with build image?
Thank you in advance for any input.
