DSP2833x adds code jump file [Copy link]

At the same time, we also need to add the jump code file DSP2833x_CodeStartBranch.asm in the original debugger project to jump to the user application process entry after the processor completes booting. The DSP2833x_CodeStartBranch.asm files corresponding to the same chip are also the same, so we can copy the file from other examples or add it ourselves. The file contents are as follows: Note: The following content is only used for TMS320F28335! ;// TI File $Revision: /main/1 $ ;// Checkin $Date: August 18, 2006 13:45:55 $ ;//####################################################################################### ;// ;// FILE: DSP2833x_CodeStartBranch.asm ;// ;// TITLE: Branch for redirecting code execution after boot. ;// ;// For these examples, code_start is the first code that is executed after ;// exiting the boot ROM code. ;// ;// The codestart section in the linker cmd file is used to physically place ;// this code at the correct memory location. This section should be placed ;// at the location the BOOT ROM will re-direct the code to. For example, ;// for boot to FLASH this code will be located at 0x3f7ff6. ;// ;// In addition, the example DSP2833x projects are setup such that the codegen ;// entry point is also set to the code_start label. This is done by linker ;// option -e in the project build options. When the debugger loads the code, ;// it will automatically set the PC to the "entry point" address indicated by ;// the -e linker option. In this case the debugger is simply assigning the PC, ;// it is not the same as a full reset of the device. ;// ;// The compiler may warn that the entry point for the project is other then ;// _c_init00. _c_init00 is the C environment setup and is run before ;// main() is entered. The code_start code will re-direct the execution ;// to _c_init00 and thus there is no worry and this warning can be ignored. ;// ;//#################################################################### ;// $TI Release: DSP2833x/DSP2823x C/C++ Header Files V1.31 $ ;// $Release Date: August 4, 2009 $ ;//##################################################################### ***************************************************************************** WD_DISABLE .set 1 ;set to 1 to disable WD, else set to 0 .ref _c_int00 .global code_start *********************************************************************** * Function: codestart section * * Description: Branch to code starting point *********************************************************************** .sect "codestart" code_start: .if WD_DISABLE == 1 LB wd_disable ;Branch to watchdog disable code .else LB _c_int00 ;Branch to start of boot.asm in RTS library .endif ;end codestart section *********************************************************************** * Function: wd_disable * * Description: Disables the watchdog timer *********************************************************************** .if WD_DISABLE == 1 .text wd_disable: SETC OBJMODE ;Set OBJMODE for 28x object code EALLOW ;Enable EALLOW protected register access MOVZ DP,#7029h>>6 ;Set data page for WDCR register MOV @7029h, #0068h ;Set WDDIS bit in WDCR to disable WD EDIS ;Disable EALLOW protected register access LB _c_int00 ;Branch to start of boot.asm in RTS library .endif ; end wd_disable .end ;//================================================ ============================ ;// End of file. ;//================================================ ============================
