Hi all,
While fighting with this A20-olinuxino nand boot process I've initially found that some essential nand-related parameters are apparently missing by default, preventing reasonable nand operation, so I started debugging this gradually.
U-Boot SPL 2019.01-rc2 (Dec 20 2018 - 16:30:46 +0300) CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 DRAM: 1024 MiB Trying to boot from NAND
Now I've discovered that SPL-build variant of sunxi_nand module is missing the sunxi_nand_init() whatsoever. Apparently it is on purpose, because:
#ifndef CONFIG_SPL_BUILD sunxi_nand_init(); #endif
And I cannot simply un-ifdef sunxi_nand_init() here, because the SPL build would fail with undefined symbol then, but I'm wondering, where are all values (like ECC strength and such) are expected to come from instead? Is SPL nand loader is supposed to be usable at all currently?
Thank you,
Regards, Nikolai
