STM32-H103 + ARM-USB-TINY : Can't probe flash

Development Boards MicroMod
1

Hi,

I just purchased those items, and after many attempts, I can’t probe the flash.

I use OpenOCD 657 and here is my configuration file :

#daemon configuration
 telnet_port 4444
 gdb_port 3333

 
 #interface
 interface ft2232
 ft2232_device_desc "Olimex OpenOCD JTAG TINY A"
 ft2232_layout jtagkey
 jtag_speed 10

jtag_nsrst_delay 200 
jtag_ntrst_delay 200 


 #use combined on interfaces or targets that can't set TRST/SRST separately
 reset_config trst_and_srst

 
 #jtag scan chain
 #format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)
jtag_device 4 0x1 0xf 0xe
jtag_device 5 0x1 0x1 0x1e

 
 #target configuration
 daemon_startup reset

 
 #target <type> <startup mode>
 #target cortex_m3 <endianness> <reset mode> <chainpos> <variant>
 target cortex_m3 little reset_halt 0
 run_and_halt_time 0 30

 
# working_area 0 0x20000000 16384 nobackup
working_area 0 0x20000000 0x4000 nobackup 
 
 #flash bank <driver> <base> <size> <chip_width> <bus_width>
 flash bank stm32x 0x08000000 0x00010000 0 0 0

When I run OpenOCD, here is what I get at the end :

And when I try to probe the flash typing “flash probe 0” in a telnet connection to port 4444, here is what I get :

What am I doing wrong ?

I made some other attempts, doing :

  • stm32x unlock 0

  • stm32x mass_erase 0

  • flash write_bank 0 main.bin 0

But it fails on timeout, according to the log :

Hello,

have you tried this?

viewtopic.php?t=10392&start=30

Just change the descriptor in config file.

Found it!

My (stupid) mistake was that I used

ft2232_layout jtagkey

instead of

ft2232_layout olimex-jtag

in the configuration file…

Now everything works so far.

Thanks for your help :wink:
