With Virtual Hosting feature, we can open/read/write files of host computer. * ICEman checks the system call and passes to GDB if it’s supported, then invokes the I/O service on the host side and sending the result back to ICEman. Turn On/Off Virtual Hosting: * Via ICEman option when initiating. --- Turn ON – “-j” or “--enable-virtual-hosting” --- Turn OFF – “-J” or “--disable-virtual-hosting” * Via GDB command during runtime. --- Turn ON – “monitor virtual hosting on” --- Turn OFF – “monitor virtual hosting off” --- Query status – “monitor virtual hosting query” Please refer this AndeSight demo project: Attachment: This demo project will open "D:\aaa.txt" file, and write/read it. "printf" will output string to file instead of UART. Note: It have to active virtual hosting in ICEman or GDB. Please new an empty file "D:\aaa.txt" first. It seens 'w+' can not create new file. The default CPU is N968A and platform is AG101P. Change "Target Chip" for other Andes CPU. Run project: Right-click on project, and select "Debug As --> (DSF) C/C++ Application" |
