Quote<xman> hi, What happens if my dram_size = 512 in [dram_para], but my board have only 256MB?<WarheadsSE> xman: which board ?<xman> https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino-MICRO/...techn_> with 256MB ram you propably need to disable mali, framebuffer and g2d.. memmap hard coded to somewhere 400-500MB<techn_> example: https://github.com/linux-sunxi/linux-sunxi/blob/sunxi-3.0/arch/arm/mach-sun5i/core.c#L222xman> 64M and 32M is for what?techn_> 64M mali, 32M for reserved framebuffer(for mali use)...<WarheadsSE> xman: then you should be enable appropriately adjust the dram para, but you might need an updated uboot that has a 256M SPL..<WarheadsSE> the Wifi has an AXP, which the Mirco doesn't.<WarheadsSE> That's a big difference....<xman> so, you edit fex, uptade kernel and update u-boot?<WarheadsSE> yes, fex change, kernel source change, u-boot source change<WarheadsSE> recompile all...<WarheadsSE> For the moment, they need to use the provided kernel source repository, and the associated uboot.
