Building Zephyr for Arty A7 100T

[marrrk]

Hi all, I've followed the tutorial on booting zephyr on the litex_vexriscv softcore up till the booting section. It seems as if everything loads fine but I get then get nothing after 'liftoff' - where I'd expert to see at least hello world.

--============== Boot ==================--
Booting from serial...
Press Q or ESC to abort boot completely.

[FLTERM] Upload complete (7.7KB/s).
[FLTERM] Booting the device.
[FLTERM] Done.
Executing booted program at 0x40000000

--============= Liftoff! ===============--

As the title says, I'm using the 100T variant as opposed to the 35T the tutorial mentions. I made sure to specify the part change when generating the gateware. I'm not quite sure where the problem could stem from.

I'd appreciate any input!

@PiotrZierhoffer @mgielda do you have some hints here?

I don't know about litex, but with Arty A7 you can run Cortex M3 on it. If you have Xilinx DesginStart, the following should work:

$ west build -b arty_a7_arm_designstart_m3 -t flash zephyr/samples/hello_world

At least you can check your hardware works or not.
