[U-Boot] U-Boot SPL 2016.09-rc1 on NTC C.H.I.P.

[Glaucio Klipel]

Hi all,

so, the difference between the 2 .config as it follows[1] and the .config
as is[2].

And the procedures:

# dd if=u-boot-dtb.bin of=/root/u-boot-dtb.bin bs=2M conv=sync
# sunxi-nand-image-builder -p 8192 -o 640 -e 0x200000 -s -b -u 4096 -c
64/1024 spl/sunxi-spl.bin /root/sunxi-spl.bin (BUILDING IMAGE FOR HYNIX
H27UBG8T2BTR-BC, VALUES FROM DATASHEET)

# for a in $(echo {0..3}); do flash_erase /dev/mtd${a} 0 0; done
Erasing 2048 Kibyte @ 0 -- 100 % complete

U-Boot SPL 2016.09-rc1-14223-gfcada3b-dirty (Aug 22 2016 - 23:45:03)
DRAM: 1024 MiB
CPU: 912000000Hz, AXI/AHB/APB: 3/2/2
Trying to boot from NAND
### ERROR ### Please RESET the board ###


I also added these lines to include/configs/sunxi_common.h[3]

With the u-boot-sunxi-with-spl.bin on a SD Card, NAND gets detected fine
and I can even boot from it.

If I add some traces in the middle of the code telling me the possible ECC
configs the SPL will try, it will print only one and then gets the error.
The stranger thing is that it will go no further in device detection to
boot, no MMC, SATA or LAN.

It produces spl/drivers/mtd/nand/sunxi_nand_spl.o, which I can see in
compilation process, later on that directory.

Hope this can help out!

Thanks in advance!
