Why do I get a STATUS_ACCESS_VIOLATION when starting nios2-terminal? - Why do I get a STATUS_ACCESS_VIOLATION when starting nios2-terminal? Description An issue has been identified where the Nios® II terminal will crash with an access violation when attempting to connect to a target JTAG UART interface when the configured buffer size is larger than 16384 bytes. The resultant error message is similar to the following: Exception: STATUS_ACCESS_VIOLATION at eip=100021F4 eax=00000000 ebx=0000000F ecx=FFFF45A9 edx=005AFFFC esi=005DE940 edi=00000000 ebp=00000000 esp=02A6CD38 program=d:\tools\altera\12.0sp2\nios2eds\bin\nios2-ter minal.exe, pid 4068, thread unknown (0x19F8) cs=0023 ds=002B es=002B fs=0053 gs=002B ss=002B Stack trace: Frame Function Args End of stack trace Segmentation fault (core dumped) Resolution To work around this issue, reduce the JTAG Uart RX and TX buffer sizes to no greater than 16384 bytes. This issue shall be resolved in a future version of the Quartus® II software.
