OPENocd with Nucleo SMT32l053

Development Boards MicroMod

Hi

Does anyone has the chance to use openocd with new nucleo stm32l053?

The idea is to use stlink v2 to flash your binary under linux env.

My current status is that I can correctly connect to the slink target.

Then flashing is not possible.

I am currently modifing openocd t add the support of the cpuid but if someone has already done the job it would be great ;)!

Thanks

Hi again

There’s no more JTAG on Nucleo stm32l053. It uses SWD only.

During the flahing procedure I can see:

"target halted due to debug-request, current mode: Thread

xPSR: 0xf1000000 pc: 0x08000f70 msp: 0x20000478

Does it mean that it is using JTAG?

I forced th use of swd in my cfg file.

Thanks

I also changed clock to use MSI instaed of HSI

in stm32lx_stlink.cfg:

STM32lx stlink pseudo target

if { [info exists CHIPNAME] == 0 } {

set CHIPNAME stm32l

}

if { [info exists CPUTAPID] == 0 } {

set CPUTAPID 0x0bc11477

#set CPUTAPID 0x2ba01477

}

if { [info exists WORKAREASIZE] == 0 } {

set WORKAREASIZE 0x1000

}

source [find stm32_stlink.cfg]

Flash base address is known by driver. Flash size will be probed.

Please note that the larger stm32lx targets (256Kb and 384Kb) uses dual

bank flash. For such targets use target/stm32lx_dual_bank.cfg.

Some samples of ST’s stm32lx chips are known to have incorrect flash size

values programmed in their FLASH_SIZE register. The driver will warn

for strange values. It is possible to override the flash size probe by

defining the correct size here. Notice though that it is the size of

the flash bank

flash bank stm32lx 0 0 <target#>

set _FLASHNAME $_CHIPNAME.flash

flash bank $_FLASHNAME stm32lx 0 0 0 0 $_TARGETNAME

proc stm32l_enable_MSI {} {

Enable MSI as clock source

echo “STM32L: Enabling MSI”

Set MSI in RCC_CR

mww 0x40021000 0x00000010

Set MSI as SYSCLK

mww 0x4002100C 0x00000000

}

$_TARGETNAME configure -event reset-init {

stm32l_enable_MSI

}
