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
Ok, discovered a special SPL-only sunxi_nand_spl variant, added some debugging, so the detection is visible:
In nand_detect_config(), start detection... Considering addr_cycles=5, page_size=2048 Considering ecc_size=1024, ecc_strength=0 failed(a). Considering addr_cycles=5, page_size=2048 rejected. Considering addr_cycles=5, page_size=4096 Considering ecc_size=1024, ecc_strength=3 failed(a). Considering addr_cycles=5, page_size=4096 rejected. Considering addr_cycles=5, page_size=8192 Considering ecc_size=1024, ecc_strength=4 good(b). Considering addr_cycles=5, page_size=8192 accepted.
I'm almost 100% sure that correct config would be page_size=8192, ecc_size=1024, ecc_strength=40 (from nand chip identification structure for regular linux kernel)
Now the detection routine in sunxi_nand_spl apparently comes up with a value of ecc_strength=4 instead... Why is that?
Thank you,
