The 2.14 CubeProgrammer is slower than the 2.8 programming speed

[xelus]

Hi, I was using CubeProgrammer version 2.8 to program the STM32L552 microcontroller, using the ‘STM32_Programmer_CLI’ file. After updating to version 2.14, I have noticed a significantly longer programming time. For example, before the update, it took 1.8 seconds to program approximately 20kB; after the update, it takes over 10 seconds. My programming settings are as follows:
call "%programmer%" -c port=swd freq=1000 -w "%hexfile%" -v

I have tried different SWD frequencies, 3300 and 24000, but no luck. Does anyone else have this issue and know the solution?

I also have one more question - if a verification error occurs, why does STM32_Programmer_CLI return 0 as the exit code? Shouldn’t it be a different value that indicates an error?
Best regards,

Hi @kweenie 

Thank you for the quick test. I was really hoping that would help with the programming time, but that would have been too simple, haven't it ?

Regarding the write protection address, it could be a real fix that has been made after v13, the only way to know is to look at the device datasheet, which is / should be the ultimate truth.

I replaced the '425' files (html or stdlr) from v13 into the corresponding v18 folders for these folders:

• C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\api\Data_Base
• C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\api\lib\FlashLoader
• C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\FastROM_Data_Base
• C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\FlashLoader
• C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\Data_Base

AND..... bham, back at 2s ???

and now ?

who can 'forward' this to ST ?

Excellent, kudos for digging deeper and getting it to work !

Then again, why should it need the files scattered in 5 different places ?

Hi Aziz,

did you notice this thread ?

Just to inform you that also v2.19 flashes the '425' chip (ID 425, STMicroelectronics, Cortex-M0+, STM32L03x/L04x/L010, ARM 32-bit Cortex-M0+) 10x slower than previous versions ?!
I think this was broken in v2.12...

Any comments on the STM side ?

Aziz (or anyone else), 

how/where can I open a support request for this (since you are not reacting) ?
