HI,

 

not able to debug the application code for arm, but able to program fpga from "program FPGA " option in xilinix tools, why is this problem occurring. Previously my board used to work properly.

Looks like you are executing the fsbl in SDK? 

There are two ways to program the ps; using the ps7_init.tcl in the debugger, or via the ps7_init.c/h in the fsbl.

The fsbl is generally used when programming via SD card or QSPI. 

 

Does a hello world application work?

 

Also, in your fsbl debug  config, try uncheck the ps7_init as this would be done in the fsbl anyway. However, as I said about fsbl from SDK doesn't make sense

Hello World program is working with QSPI mode,

but not able to program through the debugger mode. issue(Cannot access JTAG-DP: invalid ACK value (0x00, expected=0x02) Error Address = 0xf8000778 )

Hi nagavenkat@ecsonweb.com ,

Can you check the boot mode and ensure that it is in JTAG mode? Are youusing GDB or system debugger?

If this idea doesnt work, please make use of ps7_inti.tcl/.c file generated from latest version of SDK to rule out issue in ps7_init.

Regards

Praveen
