I am using the second serial interface of the beaglebone black. According 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.
