Hello,
I would like to know if there is somebody, who worked on TMS470r1a256
with WinARM or Eclipse ?
I try to write the different files :
_ standard TMS470 header file : TMS470r1a256.h
_ GNU makefile : makefile
_ startup assembler file : crt.s
_ GNU linker script file : tms470r1a256-flash.ld
_ config file for ARM-USB-Tiny : TMS470_OpenOCD-Tiny.cfg
But as I'm a very beginner, I meet many problems :
_ for the header file and the makefile, I think that it's
approximately ok
(but if somebody could check, it will be better)
_ for the crt.s, I meet problems with WinARM and Eclipse.
1. When I build there are error many error about the commands as
"b", "mov", "ldr"... I think that it's because of GNUARM, but I follow
the SPARKFUN's
tutorial(http://www.sparkfun.com/tutorial/ARM/ARM_Cross_Development_with_Eclipse.pdf).
I don't forget to add PATH. I meet this problem for WinARM and Eclipse.
2. Another problem with crt.s is I don't know how to write it
for TMS470. I don't know what and how I need to initialize.
_ for the linker script, I don't know what I must write in the MEMORY
section. In the TMS470's datasheet, I don't find adress for Memory
flash, RAM.
I don't understand how does it work.
_ for the config file, I haven't found any information.
If there are people who can help me, I'd be very happy ! It's some days
I stay at the same point :-(
Thanks a lot !
Best regards

For a part of ASSEMBLARY file (*.s) i could find in example on the web, the syntax was not digested correctly by GCC (especially comment)... Particularly when i tried to import a assemblary file from a demo running under IAR or Keil. Simply find a "good" file (written for GCC) or re-write it. Regards. Damien
Hi Damien, Thanks for your answer. But the template file *.s that I found is for the lpc2106. It's an example provided with Eclipse. So I think that it does work. And it's strange that when I build everywhere there is an assembler instruction, I've an error message. After your post, I delete all comments, and there is no change. If you or another have another idea... :( Thanks ! Regards. Thierry

(I tried to compile it for target ARM7tdmi, seems working)). You will look the syntax. Keep me in touch. Damien
Hi Damien, I can now compile with WinARM. I don't know for Eclipse, because I uninstalled it. I can compile now with the assembler file since I've taken a makefile provided for lpc2106. I modified it a little for TMS470, but I don't understand.. For the startup file, I used a file for lpc2106 (ARM7tdmi) too, but I don't understand it all. And I don't know if it is the same initialization for TMS470. Could you explain me ? Another problem is that I would like to use ARM-USB-Tiny to flash the TMS470 and not use the port com1 as it's configured in the makefile. You will find different file that I attached.
I forget to ask something more. When the compile is ok with WinARM and if I have the file .cfg, what do I have to do to flash the TMS470 with OpenOCD ? What is the process ? Regards. Thierry
Hi, I wrote the *.cfg file for openocd. I use ARM-usb-Tiny. When I execute the command : openocd-ftd2xx -f ARM_USB_Tiny.cfg I have these error messages : C:\Program Files\openocd-r717\bin>openocd-ftd2xx -f ARM_USB_Tiny.cfg Open On-Chip Debugger (2008-06-19 19:00) svn: 717 URL: http://svn.berlios.de/svnroot/repos/openocd/trunk Info: options.c:50 configuration_output_handler(): jtag_speed: 3, 3 Info: options.c:50 configuration_output_handler(): Open On-Chip Debugger (200 8-06-19 19:00) svn: 717 Info: options.c:50 configuration_output_handler(): Command info not found Info: options.c:50 configuration_output_handler(): using flash keys 0xfffffff f, 0xffffffff, 0xffffffff, 0xffffffff Info: options.c:50 configuration_output_handler(): osc_megahertz=12 Info: options.c:50 configuration_output_handler(): plldis=0 Error: jtag.c:1351 jtag_examine_chain(): JTAG communication failure, check con nection, JTAG interface, target power etc. Error: jtag.c:1556 jtag_init_inner(): trying to validate configured JTAG chain anyway...

Hi everybody, I need some help !!! I have the different files *.bin, *.cfg, *.script to flash the TMS470 with OpenOCD, but when I launch the command, I get error message. 1. I get the following message : "sector was locked", "TMS470 could not erase flash sector". 2. And another error message is : arm7_9_common.c:581 arm7_9execute_sys_speed() : timeout waiting for SYSCOMP & DBGACK, last DBG_STATUS :10 For the first error message, I try to solve the issue in different ways : 1. I used the commands in *.cfg file : flash protect in order to disable the protection for erase/writing sectors, flash erase_sector. But it doesn't work. These commands are not found. 2. Then I see in the TMS470 datasheet. there are some registers to configure to choose the location of the memory flash and to enable erase/write sectors. I wanted to configure the different registers in the assembler file *.s, but I meet some issues when I compile. And I'm not sure, it is there that I must do that. I wrote this in the _start in the assembler file : .set GLBCTRL, 0xffffffdc .set MFBALR0, 0xfffffe04 .set MFBAHR0, 0xfffffe00 // Memory Fine Base Address High Register 0 // ldr r0,=MFBAHR0 // // mov r1,#0xfffffe00 //error // and r0,r0,#0xffff0000 //error // str r0,[r1] // // Memory Fine Base Address Low Register 0 // ldr r0,=MFBALR0 // // mov r1,#0xfffffe04 //error // and r0,r0,#0xffff0384 //error // str r0,[r1] // ldr r0,=GLBCTRL mov r1,#0xffffffdc orr r0,r0,#0x00000010 str r0,[r1] // GLBCTRL4=1 For the second error message, I don't understand. If there is somebody who could help me, I will be very happy ! Thanks in advance. Best regards Thierry
