I took a backup image I had of a kali linux system from year 2022 and restored it to my small Geek+ computer where I was doing most of the work for my CHIP back when I was trying to get it booted up. As usual its kinda a mess of different things I've tried from that time, and I just don't remember everything I was doing except for what stands out in my mind is a image from joelguittet. ------------------------------------------------- https://github.com/joelguittet/meta-chip/issues/4 ------------------------------------------------- In their issue there is a conversation about the chip and differences between different versions, and they try to work out why the chip is having a specific problem that I'm not having, but it does seem somewhat related. %{-----------------------------------------------------------------+ | myfreescalewebpage writes: | | -------------------------- | | After analysis and several testing, the problem is due to | | "sunxi-spl-with-ecc.bin" file which is generated with the wrong | | NAND settings for this CHIP version, particularly OOB size is | | different. | | | | Solution applied: remove generation of the file | | "sunx-spl-with-ecc.bin" in the u-boot recipe, detection of the | | NAND characteristics and generation of the right SPL format at | | the loading process. | | | | See also joelguittet/chip-tools#1 (link broken 404 not found) | +-----------------------------------------------------------------%} Lots to learn here: ------------------ 1) what the hell are they talking about? 2) how do I build the images? 3) can I boot the image.zip contents without writing to NAND, and just use kermit to load it?
