Re: agl-minimal-image not booting with uboot if dtoverlay=pwm is added to config.txt

Hi Carles,

Firstly, as Jan-Simon mentioned, it'll be good to keep dtb load address from overwrapping with the other area. If you set uart_2ndstage=1 in your config.txt then you would see a log like following:

MESS:00:00:05.852600:0: Device tree loaded to 0x2eff4100 (size 0xbe52)

It still doesn't across the boundary right now but be quite close (0x2eff4100 + 0xbe52 = 0x2effff52), so it'll be better to change the load address to 0x2eff3100 or something. You can change it by setting device_tree_address in config.txt and also set fdt_addr in u-boot environment.

And next, the "Synchronous Abort" error would remain even if you fix the load address (because I can reproduce it locally). I'm not sure the reason but possibly pwm would cause some unhandled hardware interrupts on u-boot or has some confliction with mmc driver (because the error seems occuring during mmc initialization). I think showing verbose log in u-boot via CONFIG_LOG or something like that could be helpful.

Hello all,

sorry to insist on this topic but unfortunately the tipp provided above is not clear enough for me and I have not been able to solve this issue on my own.

Any additional advice / hints would be much appreciated.

Best regards,
Carles
