Flashing QSPI STM32

[Taisen]

HI VisualGDB,

I am trying to flash QSPI using VisualGDB, first, this tutorial is some old and not been updated. https://visualgdb.com/tutorials/arm/stm32/flash/

The tutorial is using this code to fille the OpenOCD scripts:
-c “flash bank qspi plugin 0x90000000 0 0 0 0 C:/projects/QSPIDriver/Debug/QSPIDriver.elf”
However, the OpenODC documentation told use to do like this: http://openocd.org/doc/html/Flash-Commands.html#flashdriverlist

flash bank $_FLASHNAME stmsmi 0xf8000000 0 0 0 $_TARGETNAME

First, in your code,  where is “qspi” defined?? If I use $_FLASHNAME, the system will say the Error: flash bank name ‘stm32f4x.flash’ already exists

If I change to qspi, ok, no error but nothing could be started…

The OpenODC document said Config Command: flash bank name driver base size chip_width bus_width target [driver_options]

In your tutorial, you are using four 0, but in the documentation, it only using three 0 after the address, which one is right?

The last, even if change all the code and make no error, but system still say: Failed to connecto to the debugstub, please check the gdbserver output for more detail
“flash bank qspi plugin stmsmi 0 0 0 C:/projects/QSPIDriver/Debug/QSPIDriver.elf”

Here are the log of the system:

What I should do about this??

Hi,

The “flash bank name ‘stm32f4x.flash’ already exists” error means that the FLASH name you specify is already used by the default FLASH memory bank. Simply change $_FLASHNAME to any arbitrary name (e.g. qspi). The bank name does not refer to a specific driver, instead it defines a unique name for the newly created bank.

The “Failed to connect to the debug stub” message means that GDB could not connect to OpenOCD (most likely because OpenOCD exited with an error). Please examine the OpenOCD window (or the GDBServer log in the VisualGDB error detail window) for details.

Hi Thanks for the feedback, but I am following your instruction in this page, https://visualgdb.com/tutorials/arm/memories/ and get no success.

First, where is the “plugin” device name come from? If I use “plugin” system will report error, if I use “stm32f2x” as device driver, I will get no error. But still, nothing write into the QSPI.

-c “flash bank qspi stm32f2x 0x90000000 0 0 0 0 C:/VisualgdbProjects/QSPIDriver/QSPIDriver/Debug/QSPIDriver-QUADSPI.bin”  -c “init” -c “reset init”

I tried use the github file to repeat your results, https://visualgdb.com/tutorials/arm/stm32/flash/

But when I do the “TestFLASHProgramming(0x90000000, 0);” the system will not write anything into QSPI, could you try to follow your guild and repeat it again? I already tried several time with no success…

I am following your guild step by step for two samples, only one different is here, the “plugin”, in my case, I always report error, so, I have to use “stm32f2x” as driver name

Here is the steps I am following you guild, but still nothing write into the QSPI

As you could see, I copyed the QSPIRoutines.cpp file

I added the script as reference told

add the external memory

 

Here is finial results, as you could see, the memory still nothing and the address is 0x90000000.

I figured out some error in my code, I am using stm32F769I-Disco, but the board support for QSPI by VisualGDB is STM32F7469G, which is 128M not 512M, BUT, still flash nothing on the QSPI.

Hi,

Looks like there is a confusion about the “stm32f2x” vs “plugin” driver. The “stm32f3x” driver is a built-in OpenOCD driver that is only capable of programming the regular on-chip FLASH memory. Hence if you specify “stm32f2x” in your command, OpenOCD will try to use that driver and fail.

The “plugin” driver is a special driver only supported by our OpenOCD fork that will load your ELF file (that must include certain symbols) into the device and call functions from it to program the memory. The error message in one of your previous posts actually contained a clipped line “Invalid FLASH plugin”. Please switch back to using “plugin”, get that message to appear and check the rest of that message. It should provide a clue on why the ELF plugin could not be loaded and resolve the errors mentioned there in order to get it working.

Hi VisualGDB Team, Yes, after I change that back to plugin, the system return this messages:

Here is my setup for the flashing command.

Hi VisualGDB Team, I am little confused about this two tutorials: https://visualgdb.com/tutorials/arm/stm32/flash/ and https://visualgdb.com/tutorials/arm/memories/

I am following  https://visualgdb.com/tutorials/arm/stm32/flash/ this driver tutorial, and at this point, at the very end of the tutorial, it back to another External Memory tutorial… Should I add all the drivers into the External Memory project, which means I should copy all the FLASHPluginCommon.cpp file into the External Memory Tutorial to make the

-c “flash bank qspi plugin 0x90000000 0 0 0 0 $(RemoteSourceDir)/$(ConfigurationName)/$(TargetFileName)” -c “init” -c “reset init” code work???

In the flash Driver tutorial, I could using Quick Setup OpenOCD to flash run TestFLASHProgramming(0x90000000, 0); (NOT the -c “flash bank qspi plugin 0x90000000 0 0 0 0 $(RemoteSourceDir)/$(ConfigurationName)/$(TargetFileName)” -c “init” -c “reset init”), I could flash the RAM with NO error, but when I using Memory Tool to look into the 0x90000000, there are all zero.

If I using the STM32 ST-Link Utility to check the memory, yes, I has been changed, why? Why the Memory in the VisualGDB Does NOT work?

Could you make this two tutorial clear? Do I need to copy all the FlashPluginCommon.cpp to the External Memory Tutorial??

Hi,

OK, thanks, the issue was caused by the FLASH initialization code timing out. We have fixed this in an update to our OpenOCD package and also updated the flash_drivers examples to specify the timeout values instead of hardcoding them in OpenOCD.
