STM32 MCUs Security

Hello I am writing to express my complete disappointment regarding how the "sits" are assigned to the workshops, several times I have expressed interest in participating in the hands on (I'm a firmware developer) and in all cases the answer was a refusal due to lack of sits and in more than one case other people that I have sent the email prompting the workshopto, despite having signed up afterwards, were accepted. Given the treatment received, the temptation to switch to another brand is really strong​Best​ regardsGMG​

I protected the flash from code running on the MCU using HAL, but while trying to unprotect it using STM32CubeProgrammer the board could not be unprotected ("Expected value for Option Byte "RDP": 0xAA, found: 0xBB") and became unresponsive. After this, I can not even connect to the board anymore. I believe this is the second time this happens, the first time I thought it was a hardware problem, but this time luckily I was using verbose level 3 and got a log, that is attached.I have tried to power down the board completely, and also to connect using a JLink programmer, but it did not work.Surprisingly, I had no problems with a STM32WB55 MCU.Does anyone know anything about this problem?

Hi,Thanks for releasing the SBSFU version 2.4.0.Could you please let me know if it possible in this version to download the FW file to NOR flash.I would like to use NOR flash as Download slot. If it is possible, could you please give me an short overview on how can I achieve this.Thanks,Ankush

Hello, I'm sorry but I too have missed the confirmation email! Am I still in time to confirm?Thanks!

So far I have not received the development boards, could we verify the shipping adress and status?

HelloUnfortuneatly I have not read the confirmation email in time and would still like to join the workshop on the 10th of November. If possible please sign me up again.Thank you in advanceBest wishesPhilipp

Hi partners, I missed to confirm my registration for the workshop "Discover our STM32 security ecosystem - from theory to practice" for November, 4th. Is it possible to still join the online workshop?Thanks for your time.Sincerely,Raúl

Hi, I was registered before for the course on Tuesday October 6th and had to cancel as I did not receive the hardware in time. It actually was sent 2 days late to a wrong address in Germany instead of Switzerland. Also for the course on October 27th I did not receive the boards until now. When will the boards be send?

Because I was on a 10 day vacation, I missed to confirm my registration for the workshop "Discover our STM32 security ecosystem - from theory to practice" within the prescribed time frame. Might it be possible to still join the online workshop?Best regards;M. Roggon

Good Morning, I missed confirming my registration for the workshop "Discover our STM32 security ecosystem - from theory to practice" within the prescribed time frame. Might it be possible to still join the online workshop?Yours faithfullyC. Schermesser

I'm trying to set the Read projection level to 1 after programming the application. Our manufacturing setup requires that we use J-Link rather than the ST-Link. I tried making a set of exit steps for the J-Link but it isn't working; I'm wondering if anyone can suggest modifications that might make it work

Dear,I am setting RDP to level 1 in my application, After setting it I call System reset HAL_NVIC_SystemReset(); After reset I am expecting the MCU is locked, but it seems I read in code the MCU is still in level 0 so the procedure of setting RDP to level 1 is repeating. Only power disconnect locks the processor to level 1.Any solution?Best regards, Jan. HAL_FLASHEx_OBGetConfig(&flashTemp); if(OB_RDP_LEVEL_0 == flashTemp.RDPLevel) { HAL_FLASH_OB_Unlock(); HAL_FLASHEx_OBGetConfig(&pOBInit); pOBInit.RDPLevel = 0xBB; pOBInit.WRPState = OB_WRPSTATE_ENABLE; HAL_FLASHEx_OBProgram(&pOBInit); HAL_FLASH_OB_Lock(); HAL_NVIC_SystemReset(); }

I did expect this to be development platform neutral but had to find out that I will not be able to participate since I don't use Windows.

Hello,during my holidays I missed the confirmation email for the german workshop on Oct, 8. 2020.Please rebook for the german workshop on Nov., 9. 2020.I've already received the kit.Best regards

Hello,I am working on an offline SWD programmer for a test jig, it is based on the widely available DAP open source implementation for ARM and it works fine so far however there is no command for dealing with option bytes and specicially with RDP, in my case the vast majority of time i only need to set RDP to level 1 after flashing but in some occurences i need to disable RDP (set to level 0) in order to reflash the target.And that is where is have an issue.To clarify the setup : The programmer is based on an STM32F411CEU6 which is the main MCU of the test jig control board, it also perform programming of other chips as well as some unitory testing (test pads and RF front end). The SWD programming of the target is done via SWD, i added a line for the STM32F411 reset just in case. The firmware file is in an SDHC card (SDIO 4bit).The target is also an STM32F411CEU6, it is programmed with a firmware or ±360KB, verified and the RDP should be set to level 1.In some case the device has been

Hello,during my vacation, I missed the confirmation email for the workshop on October 8th. I would still like to participate if possible. The dev kits have already been sent to me.Thank you

Good day everyone,I'm looking for STM32L082 code examples to use its AES peripheral.Does anyone have something that could help? I had alread searched the internet, but could not find code examples anywhere.I'll be greatful if anyone could shed some light.Thank you.Best regards,Ulisses

I have a recent download of en.x-cube-cryptolib_3.1.0.zip and en.patchx_cryptolib_3-1-3.zip.The former contains AccHw_Crypto subdirectory with subdirectories for F2, F4, F7 and so on but no H7.Subdirectory for H7 exists only under Fw_Crypto.In en.patchx_cryptolib_3-1-3.zip there are subdirectories for G0, G4, L5, WB and H7A3. All these, I guess, are software only?Which package contains hardware accelerated library (AccHw_Crypto) for H753 ?Thanks,-- pa

Trying to fill in and submit it, but it demands an Application, that has to be selected from a drop down list instead of entered as text, and the list is empty so even submitting the form is impossible.
