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: Path: /bin/busybox CPU: 0 PID: 97 Comm: modprobe Not tainted 4.4.0-rc1 #26 task: 9f1f9c00 ti: 9f1ba000 task.ti: 9f1ba000 [ECR ]: 0x00220200 => Invalid Write @ 0x00000000 by insn @ 0x80a8a8c2 [EFA ]: 0x00000000 [BLINK ]: ufshcd_release+0x14a2/0x1738 [ufshcd] [ERET ]: __mutex_lock_slowpath+0x46/0x100 [STAT32]: 0x0000080e : K A1 E2 E1 BTA: 0x70054f4e SP: 0x9f1bbc64 FP: 0x00000000 LPS: 0x808765b8 LPE: 0x808765bc LPC: 0x00000000 r00: 0x9f2b5b50 r01: 0x9f1bbcb4 r02: 0x00000000 r03: 0x9f1bbc64 r04: 0x00000000 r05: 0x00000002 r06: 0x6affd617 r07: 0x00000000 r08: 0x6affd617 r09: 0x00000000 r10: 0x00000008 r11: 0x0000403f r12: 0x00000000 Stack Trace: __mutex_lock_slowpath+0x46/0x100 ufshcd_release+0x14a2/0x1738 [ufshcd] I would like to hear some opinions about this issue!
