; -------------------------------------------------------------------------------- ; @Title: Linux Demo for TRACE32 OS Awareness on the phyCORE-PXA270 ; @Description: ; This batchfile demonstrates the use of the OS Awareness for Linux ; The example is generated for a phyCORE-PXA270 board using an ICD. ; It will NOT run on any other board, but may be used as a template ; for others. ; Linux is downloaded to the board via ICD. ; @Keywords: awareness, phycore, pxa*, RTOS ; @Author: DIE ; @Board: phyCORE-PXA270 ; @Chip: PXA270 ; @Copyright: (C) 1989-2019 Lauterbach GmbH, licensed for use with TRACE32(R) only ; -------------------------------------------------------------------------------- ; $Id: pxa270_linux.cmm 15223 2019-11-05 16:29:45Z bschroefel $ ; Starting Linux example with TRACE32: ; - Connect terminal (NULL modem cable) to FF-UART (115200-8-N-1-N) ; - Start TRACE32 ; - (T32) do linux ; - start "hello" LOCAL &ka_path &awareness LOCAL &srcdrive LOCAL &srcpath &srcdrive="S:" &srcpath="&srcdrive"+"\" SCREEN.ON ; Debugger Reset WinPAGE.RESet AREA.RESet WinPOS 0. 26. 75. 7. 0. 0.
