How to solve "Host filesystem not supported when direct drivers are used"?.
I want to use the generic serial flash interface to access the configure flash ROM and use a JTAG cable to read the data to PC host and save it to PC.
The source code about file access is :
fp = fopen("/mnt/host/epcql256.bin", "w");
I checked the hal.enable_small_c_library and hal.enable_reduced_device_drivers .
When I compile the program , it has a error
"Error: Host filesystem not supported when direct drivers are used."
If I don't check hal.enable_small_c_library , the error is "address 0x201f324 of gflish.elf section `.rwdata' is not within region `main_memory" , the device is arria10 10AS048H4F34E3SG , it has not enough memory to address 0x201f324 .
