Running the Homework for the L5 Board a second time. Now i get errors

Hi.,

Because i wanted to verify if the processes worked as well on my work provided Laptop. I ran the homework a second time.

The TFM Homework of course resulted in mutliple Errors and nothing worked. But now i can't even use the L5 Board anymore. I get no output on the Serial and the usb part shows a fail.txt with the following content:

The interface firmware FAILED to reset/halt the target MCU

Trying to connect the STCubeProgrammer also now fails with: DEV_TARGET_NOT_HALTED

So i can't manually wipe the device and restore it again.

Quick help would be appreciated.

Hi,

if you launch the STEP1_prepare_L5_for_TFM.bat to you see any error ? If yes, could you show the log.

Please launch a command line and do this :

cd C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin

STM32_Programmer_CLI -c port=SWD mode=UR -ob displ

And share the result, this will allow me to understand your option byte configuration.

 The target doesn't want to connect to the CubeProgrammer anymore.

Ok Thanks to support i now got my solution:

  • Connect CN11 Pin 5 and Pin 7
  • Press reset
  • run
 .\STM32_Programmer_CLI.exe -c port=SWD mode=HotPlug -ob displ

now you should see some output.

  • run
STM32_Programmer_CLI -c port=SWD mode=HotPlug -ob RDP=0xAA

Optionally(not verified if it is the solution):

try running:

STEP9_remove_TrustZone.bat

it should work(while blue and red led are shining)

to reinstall the working state for the homework run step 1 and step2 batch files again

To complete the previous message, the issue was due to the fact RDP level has been set to 0xBB ( level 1) with an empty flash.

To be able to connect we needed to activate embedded bootloader to connect and set the RDP to level 0.

Then connection is now possible.
