15:50 <filippo> Hello! I'm having an issue with a sunxi device on which I am trying to install a new version of u-boot. I've compiles u-boot successfully on my main machine, using `make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16` and the CHIP_defconfig configuration. I am then testing it before flashing using `sunxi-fel -p -v uboot u-boot-sunxi-with-spl.bin`, but from the serial port it's stuck on `Trying to boot from FEL`.

15:50 <filippo> ANyone that can help me, please? Thanks¬

15:59 <apritzel> filippo: which version of U-Boot is that? there were bugs with FEL lately, which we (hopefully) fixed

16:01 <filippo> oh, ok. I'm using 2022.04

16:01 <apritzel> filippo: can you try the very latest version (v2022.07-rc6)?

16:01 <filippo> ok, one sec

16:02 <apritzel> filippo: in particular this commit is probably helpful: https://source.denx.de/u-boot/u-boot/-/commit/e008e5132f7e1

16:03 <filippo> That fixed it. Many thanks

16:04 <apritzel> filippo: cool, thanks for testing! Please report any issues you see, especially with the CHIP, as this one is a special snowflake

16:07 <filippo> Sure I will! Indeed, it is quite difficult to work on that thing due to the weird Nand and no SDcard

16:12 <apritzel> filippo: yes, it's basically the only among the 160 sunxi boards without MMC (and this is what caused the bug, actually)

16:13 <apritzel> filippo: but this is the non-pro version of the CHIP you are using, right? The one with MLC NAND?

16:19 <filippo> yes, the one with MLC nand

16:19 <filippo> and that's what I'm trying to initialise now in uboot

16:39 <apritzel> there was some fix last week for NAND loading: https://patchwork.ozlabs.org/project/uboot/patch/CAHpJTQqVxTgAmU4ZOyCKg8o1YECaefBagqBNSNHFfC1UpT2r6Q@mail.gmail.com/

16:39 <apritzel> but IIUC that's independent of the MLC/SLC issue

16:40 <filippo> cool! yes, nand loading seems quite diffcult on MLC

16:40 <filippo> I'm considering swapping the nand for a SLC

17:13 <filippo> So, I have setted the pagesize/eraseblock size for the nand. When I try to boot it now, I see no mtd or nand device available. Any idea?

17:29 <filippo> Nevermind, I discovered it's related to the device tree. Copying the &nfc block from the kernel dts file fixed it (and editing some pin names in the new file)

23:04 <filippo> Hello! I am having some issues compiling u-boot. In particular, I get some issues on spl_ubi.c, with undefined reference to nand_spl_read_block. Any idea on how to fix this? I was thinking about an isue with the configuration...
