On the TS-4800 device, the 5.4 kernel receives an error related to the memory definition on the device. As I understand it, something needs to be included in the kernel, but I can’t understand this. Maybe someone based on an error can tell? The log shows that the device starts, but it is on the memory that an error occurs. Thanks in advance.
