Question, i.MX6SL Errata ERR005778 (2)

Dear team,

I would like to ask about the way of workaround ERR005778 MMDC of i.MX6SoloLite.

After reading your LinuxBSP, my customer believes that watching FRC_MSR is needed in the workaround procedure even though errata document(IMX6SLCE, Rev.4) does not mention about FRC_MSR.

Is it true?

Thanks,

Miyamoto

Hi Miyamoto

you are right errata document just gives general stepts, full

implementation is given in macro mmdc_clk_lower_100MHz (it uses FRC_MSR) :

file arch/arm/mach-imx/lpddr2_freq_imx6.S

linux-imx.git - i.MX Linux Kernel 

Best regards
igor
