What is the correct way to test in RAM before flashing? Problem being a wrong flashing bricks target (I do have means to recover bricked targets, but not here). > Have you actually tried to write u-boot-with-spl.bin to SPI flash? The Yes I did and it didn't work :( That's why I'm trying to chain load in RAM as I do NOT have a JTAG debugger, unfortunately. > only result I can see from your test is that U-Boot crashed after the > go command and the CPU simply booted again from the currently flashed > 2020.04-rc1 image. Only the last test resulted in a permanent hang. No, I was not clear. First test was fully functional. I willingly rebooted from SPI NOR in order to do the second test in the same condition. Second test crashed immediately. > The final version mtmips SPL series (which got merged) was also tested > by Stefan Roese so it should simply work on your VoCore2 board. > > You could also switch to tag 2020.07 and test that. It could also be > possible that something else got broken since 2020.07. I will do that test ASAP. I assume You mean I should Flash "u-boot-with-spl.bin" to SPI NOR, right? Do You have any hint why "u-boot-with-spl.bin" is substantially larger than "u-boot-mtmips.bin" with essentially the same defconfig? I am switching also because I need SquashFS support; do You have any idea how stable is that? (I need it to load Linux Kernel). Many Thanks in Advance Mauro P.S.: "daniel666" on IRC is You?
