Hello everybody,
I am working on a STM3210E-EVAL board for 2 weeks now and there are some
odd things happening when I use the GDB provided with WinARM(gdb version
6.4.50.20060226-cvs).
I use Eclipse as a IDE, everything seems to be working fine until I
reach some instructions that need to work with register R7('mov.w r7,0'
or 'mov.w r7,r7,#12', also an add.w r7 creates the same outcome), I took
a look on the packages sent by gdb and this is what it sends:
Sending packet: $m2000037e,2#8c...Ack
Packet received: 80bc

Sending packet: $m20000322,4#56...Ack
Packet received: 07f10c07
Sending packet: $m3c,4#63...Ack
Packet received: E0E
The "Sending packet: $m3c,4#63...Ack" is what actually this error is
about, normally that package should not exist and it happens only when I
try "mov.w r7,0", if I try "mov.w r1,0" this packet doesn't get sended.
Everything works fine(single stepping,watches,and so on) except for this
problem.
Any ideas?
Thank you in advance!

The tools in WinARM (even in the "latest" test-release) are a little outdated. I currently do not plan to build a new WinARM since Codesourcery's package includes everything I currently need for my hobby and professional work. I suggest to try again with the tools from Codesourcery (arm-eabi "bare metal" for Win32 hosts). The lite version is free. For a quick start just install the Codesourcery package and replace the prefix for all GNU tools with arm-none-eabi-, i.e. arm-elf-gdb (WinARM) -> arm-none-eabi-gdb (CS). Maybe the information in this project will help: http://www.siwawi.arubi.uni-kl.de/avr_projects/arm... During development I have used Eclipse Ganymede, CDT, CDT hardware-debugging-plugin, Codesourcery G++ lite for ARM-eabi 2009Q1, OpenOCD (different but rather up-to-date versions), Amontec JTAGkey, FTDI-drivers and STM32F103CB for the tests. Debugging from Eclipse works as expected (well, at least what I expected/needed). A little bit of additional information can be found in the readme.txt.

Hi Martin, Thanks for the reply, I will try this. Regarding the following: "During development I have used Eclipse Ganymede, CDT, CDT hardware-debugging-plugin, Codesourcery G++ lite for ARM-eabi 2009Q1, OpenOCD (different but rather up-to-date versions), Amontec JTAGkey, FTDI-drivers and STM32F103CB for the tests. Debugging from Eclipse works as expected (well, at least what I expected/needed). A little bit of additional information can be found in the readme.txt." I am also using Eclipse Ganymede CDT, Codesourcery G++ Lite for ARM-eabi 2009Q1, OpenOCD but with an Olimex ARM USB OCD. For debugging I used the gdb from WinARM since it was the only one I could configure and did all the stuff I needed. I will try with the gdb from Codesourcery although that gdb never worked properly when I tried it(today,it executes stept by step but doesn't show me the registers and when I hit run to execute the code until a breakpoint everything goes south when I do this). I will have a look at your example. Thank you! Lucian P.S. I am also using CS-EP9302 from olimex and I never had a problem with the gdb(arm-elf-gdb).

So I have used the one from DevkitARM for some time (both are cross-toolchains for arm-eabi targets). But so far I have had no problems with the gdb from G++ 2009Q1. Do you use CDT gdb hardware debugging plugin or the Zylin plugin? Both are similar but not the same. Olimex ARM USB OCD and Amontec JTAGkey are very similar (I don't own an Olimex interface). As far is I know the only differences are the routing of the reset-lines to the FT2232 and different level-convertes (JTAGkey can handle lower target voltages). OpenOCD also plays an important role and is still under heavy development. If you are using an old version please try with a new one (maybe even a binary compiled from the SVN sources). I'm currently using OpenOCD SVN2660 with FTDI-Drivers from 2/2009. > I will try with the gdb from Codesourcery > although that gdb never worked properly when I tried it(today,it > executes stept by step but doesn't show me the registers and when I hit > run to execute the code until a breakpoint everything goes south when I > do this). > I will have a look at your example. Not related to debugging: There is one know issue with the current release of my STM32 SD demo: If you see errors about missing files in ...dep... during make please create a directory FLASH_RUN and a subdirectory dep in it. I will upload a package with a fixed makefile soon. >... > P.S. I am also using CS-EP9302 from olimex and I never had a problem > with the gdb(arm-elf-gdb). So far I have not "played" with Cirrus devices. I expect the older gdb-version have been heavily tested with "mature" ARM-cores like the ARM9 in the EP9302. CM3 is a rather new core so maybe there are some minor glitches. Good luck, Martin

Hi Martin, Yes, I am using the CDT from Zylin, I've tried both CDT gdb hardware debugging and Zylin, so far I am working with the one from Zylin(I've tried the CDT gdb hardware debugging with the gdb from Codesourcery and that didn't work to well). I will try some things today, hope everything works fine. Thank you! Lucian

Hi Martin, Tried some things today,everything worked fine for an hour or so with the gdb from your example (Devkit) now I get the same problem at "mov.w r7,0". :-) I'll try to compile a newer version of OpenOCD although when I do a step by step operation with openOCD using telnet this problem doesn't occur. Thank you for everything!

Hi, Worked with the Codesourcery gdb and this one "cracks" always at instruction "bx lr", I checked the lr register and other registers and everything is ok.

I've now compiled a new version of OpenOCD svn 2681. Now I'm looking inside the lst file,since I saw a problem in the disassembly window with the debuger the code corrupts my stack. I must say that things don't look the same now. It passes that issue with the "mov.w r7,0" but it corrupts my stack by having different instructions. Odd things are happening :-). >LST file: *(__IO uint32_t *) tmp |= EXTI_InitStruct->EXTI_Line; 20004fca: 68f9 ldr r1, [r7, #12] 20004fcc: 68fb ldr r3, [r7, #12] 20004fce: 681a ldr r2, [r3, #0] 20004fd0: 687b ldr r3, [r7, #4] 20004fd2: 681b ldr r3, [r3, #0] 20004fd4: ea42 0303 orr.w r3, r2, r3 20004fd8: 600b str r3, [r1, #0] 20004fda: e00f b.n 20004ffc <EXTI_Init+0x148> >Disassembly window: *(__IO uint32_t *) tmp |= EXTI_InitStruct->EXTI_Line; 0x20004fca <EXTI_Init+278>: ldr r1, [r7, #12] 0x20004fcc <EXTI_Init+280>: ldr r3, [r7, #12] 0x20004fce <EXTI_Init+282>: ldr r2, [r3, #0] 0x20004fd0 <EXTI_Init+284>: ldr r3, [r7, #4] 0x20004fd2 <EXTI_Init+286>: ldr r3, [r3, #0] 0x20004fd4 <EXTI_Init+288>: orr.w r3, r2, r3 >0x20004fd8 <EXTI_Init+292>: ldr r7, [pc, #896] (0x2000535c <GPIO_Init+208>) >0x20004fda <EXTI_Init+294>: movs r0, #0 It seems that my main.bin file is corrupted: 00004fd0: 7B 68 1B 68 42 EA 03 03 0B 60 0F......
