Android version is ICS, NXP patch name is imx-android-13.4.1.
Target platform is custom board of epdc system on i.MX6DualLite.
The configuration is two Micro 1GBx32 LPDDR2 in a dual-channel interleaved, 64-bit wide memory system.
We donwloaded patch files on the following site, files are 0001-Support-LPDDR2-on-6DL-platform_Uboot and 0001-Support-LPDDR2-on-6DL-platform_Kernel, and applied.
But after lpddr2 frequency change from 24MHz to 400MHz, kernel frequenctly freeze with dump messages.
We removed CON_REQ bit control of MMDCx_MDSCR register when lpddr2 frequency change entry and ext (file:arch/arm/mach-mx6/mx6_lpddr_freq.S), and it appears to be stable.
We refered to fsl-yocto-L4.1.15_1.2.0-ga.
Please tell me whether CON_REQ bit control of MMDCx_MDSCR register is need or not.
We think that this control is need... why did you remove this control on fsl-yocto-L4.1.15_1.2.0-ga ?
