memtool reading IPU registers hangs

qufeiwang — Thu, 01 Dec 2016 16:27:54 GMT

on a custom board, the memtool reading IPU1 and IPU2 and VDOA modules hangs. Most other modules work fine.

[root@freescale home]# ./memtool IPU1.*
./memtool IPU1.*
SOC is mx6q

IPU1 Addr:0x2400000

I did enabled the all clocks as Yuri said, using the following lines:

./memtool 0x020c4068=0xffffffff

./memtool 0x020c406c=0xffffffff

./memtool 0x020c4070=0xffffffff

./memtool 0x020c4074=0xffffffff

./memtool 0x020c4078=0xffffffff

./memtool 0x020c407c=0xffffffff

./memtool 0x020c4080=0xffffffff

thanks a lot!

Hi Oufei

clock gating is described in sect.18.6.23 CCM Clock Gating Register 0 (CCM_CCGR0)

i.MX6DQ Reference Manual

http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf

what BSP are you using, please try

linux-2.6-imx.git - Freescale i.MX Linux Tree

use imx-test (memtool)

thanks igor,

I am using a file given by the chip distributor.

L3.0.35_4.1.0_130816_source

Looks like I need do a clean start from scratch. I am new to IMX.

Is yocto the officially recommended ?
