Subject: UFS: MPHY configuration issue
Date: Wed, 20 Jan 2016 18:57:15 +0000 [thread overview]
Message-ID: <569FD88B.1010407@synopsys.com> (raw)
Hi,
I am trying to configure my MPHY through UNIPRO but I am experiencing a kernel
crash when executing a dme instruction:
As an example I am executing the following:
result = ufshcd_dme_set(hba, UIC_ARG_MIB_SEL(PA_RXHSUNTERMCAP, 0), 1);
In ufshcd_dme_set_attr() I have the following data ready to execute:
set = dme-set
uic_cmd.command:2
uic_cmd.argument1 = 15a50000
uic_cmd.argument2 = 0
uic_cmd.argument3 = 1
And then the ufshcd_send_uic_cmd() procedure originates a crash as you can see
below.
Crash log:

I would like to hear some opinions about this issue!
Thank you very much!
