Hi, thank you for the advice on the mmu config which we missed. One has to enable the device memory region as follows: arm_cp15_set_translation_table_entries(device_addr_start, device_addr_end, ARMV7_MMU_DEVICE); Afterwards one can access the device memory as described before. We use a nig

Hi, currently we experimenting with the RTEMS-5 on a Cylcone V SoC-FPGA using the altcycv_devkit BSP. Now we are trying to access a simple hardware module connected to the HPS2FPGA Bridge via an AXI interconnect. Our approach of simply write data to the corresponding address or using the 'alt
