hi. is there a prebuilt image for koheron250-4 using 1gb som? i tried to build one, it did not work. :(

just the content of the /boot would be good..

best regards rashed

I merged #621 and built the image (not tested). You can download it here: https://assets.koheron.com/sdk/images/koheron-alpha250-4-1g_v0.24.zip

sorry, that did not boot. same as the one we were trying to make.

i do have a working kernel, not sure when i made it, but it comes up with error: "cdns-i2c e0004000.i2c: timeout waiting on completion" probably a device tree error, so wanted to remake it.

this is a mars zx3, right? So i theory should be able to just make the kernel from their petalinux sources?

EDIT. e0004000 is disabled inside the device tree that the sdk currently is uusing

this entry is in spi.tcl for alpha250-1g make_bd_intf_pins_external [get_bd_intf_pins ps_0/IIC_0]

but it does not exist for alpha250-4-1g. are we using the iic for anything, maybe the eproom or something similar?

EDIT: solved the issue by adding exporting the pin and editing the port.xdc to change iic_0 to IIC_0

this is kernel 5.4.0-xilinx, made using koheron 2020.1 branch some the yesterday, but I needed to use a very boot.bin, which I don't remember when and I made it. so would be nice to investigate why the new FSBLs builds don't seem to work.
