[U-Boot] PLL cpux allwinner H3

2017-10-22 Thread Mark L .
Hi, The formula for the PLL CPUX output is (24Mhz * N * K) / (M * P). Is there a problem applying N = 32 && K = 2 instead of N = 16 and K = 4 (M and P being equal)? I am asking if there is a pattern to respect or not at all. Thanks --  Mark ___ U-Boo

[U-Boot] Vexpress-ca9x4: huge size

2017-01-10 Thread Mark L .
Hi, Once compiled, the u-boot.bin for vexpress-ca9x4 is 267,424 bytes on disk. In memory, it occupies 332,957 bytes (mallocs and so on). To me, it is HUGE. Is there a problem with my build, or is it normal? My compilation commands: make ARCH=arm CROSS_COMPILE=~/Downloads/gcc-arm-none-eabi-5_4-2
