Yep, I did this. The code boots correctly and the device is recognized. The
serial is still not working, I assume this is a matter of code right now.
Thanks!

I think you need to add a line in
kernel/src/plat/am335x/machine/hardware.c
for this.

I am using the second serial interface of the

to the source code (in
libsel4platsupport/plat_include/am335x/sel4platsupport/plat/hw/soc_AM335x.h),
the address is 0x48022000). The following line is found in the source
#define SOC_UART_1_REGS (0x48022000)
So, in CAmkES, I configure the hardware component that represents the
serial hardware component with the following attributes:
drv.mem_attributes = "0x48022000:0x1000";
The application compiles fine. However, when launching the image on the
target, I have the following issue. Any idea about how to solve this? Does
anybody successfully used UART1 on the beaglebone black? Or have any
idea/suggestion to investigate?
Thanks.
Julien.
