Hi Guys,
First time poster so my apologies if I am in the wrong place, and I like
to thank all the developers and contributors to OpenOCD, you guys rock!
This is a little issue I am facing, and I ran out of ideas.
I am an active windows user, with the classic Eclipse/GDB v7.41 for windows
(Linaro package) , using ARM STM32 F429. My little board is the all new
F429-discovery from STMicro (
www.st.com/web/catalog/tools/FM116/SC959/SS1532/PF259090?icmp=stm32f4pr_pron_p3436s_sep2013)
, using the F429ZI with 2MB of flash and 256K of RAM and STLINK/V2 onboard.
I am using Freddie distribution of OpenOCD v0.7, with everything as is all
defaults. For this connection to st-link i am using target
stm32f4x_stlink.cfg (default as is) with the stlink-v2.cfg as interface.
First, the good news: My application is a little bit over the 1MB of flash,
if i reduce my code to slightly less than the 1 MB flash, all works OK,
everybody is Happy :). But if i increase my application to over the 1MB
mark (normal user code nothing fancy), when I download to target using
STLINK/V2 of the new discovery board, i get the following errors :
Error: address range 0x08000000 .. 0x0811ffff is not sector-aligned
Error: flash_erase returned -904
Observations:
- note that openOCD probe got the flash size right, 2048K.
- I tried forcing the correct base and size :
flash bank $_FLASHNAME stm32f2x 0x08000000 0x200000 0 0 $_TARGETNAME
OpenOcd captured the correct base and size, but error remains.
- of course GDB did not load nor erased the STM32F429
- the error in GDB : Error erasing flash with vFlashErase packet
- The size over 1MB is just my theory, and my observation, not sure if it
make any sense.
- I can send a debug output with -d but I thought to try the soft approach
first, maybe it is a known issue and the fix is silly.
Any idea? did somebody got this before, I know from search this showed up
previously for the STM32L in older v 0.4. I am ready to implement any
suggestion (I am using the .cfg file so if any suggestion please consider
inserting commands or settings in the .cfg file).
My startup commands in GDB TAB (before loading) are:
monitor reset init
monitor flash probe 0
monitor flash info 0
monitor soft_reset_halt
Like I said for an application <1MB, the same exact .cfg files, settings
and setup work well, never had any download issues with any ST target
using STLINK-v2.
Any help is appreciated,
Cheers, and thanks in advance.
Randy.
