; @Title: FDX Tracing Demo for ARM7/9/11, XSCALE, CortexA/R/M (32/64-bit)
|
|
; @Description:
|
|
; This script shows how to use the FDX communication on ARM.
|
|
; The demo code is compiled as position independent code and should run on
|
|
; every ARM platform. Per default we use DCC as transfer channel. As e.g.
|
|
; CortexM does not support DCC, we use the RunTimeMemoryAccess to
|
|
; demonstrate FDX on CortexM.
|
|
; For more information about FDX, please refer to general_ref_f.pdf
|
|
;
|
|
; Prerequisites:
|
|
; * System is connected
|
|
; * RAM is accessible Read/Write/Execute
|
|
;
|
|
; Usage:
|
|
; DO ~~/demo/arm/fdx/fdxtrace <RamStart>
|
|
; e.g. DO ~~/demo/arm/fdx/fdxtrace 0x1000
