Hi,One of the requirement for the FLASH layout on dual bank product (like the STM32L4 that I use) is that the FWALL code section overlaps the the FWALL NVdata (see the attached image). If I understand correctly the reason is that if the banks are swa...
Hello everyone I am working on 1 image example for STM32G474 I want to ask that what we can achieve using this.....We are able to download new firmware image or Not ?????????
@Jocelyn RICARD We need secure storage to keep Private Keys and certificates for TLS communication on STM32H753.To achieve this we found STSAFE-A110, but interfacing and to bring in this peripheral, it is time taking in terms of re-spin PCB design...
One of the variable in my program is the program version ie 200 for version 2.00. I log it to my debug log and I display it for the customer. The program version must also be passed to the SBSFU post build script. Is there any way to do this so the S...
I'm using for the first time the RNG of STM32H753. I have a "clock error" which means that rng_clk is too slow compared to HCLK.The reference manual mentions the following: Is it a problem to just disable the clock error detection since it seems that...
My read protection is on and i can't turn it off by any tool.Hope i can get some help
Following this question, I am also confused about how to fill the key in the CRYP peripheral. I don't find the Ref Manual very clear The register description mentions the key as an array K and an array b where MSB of K are in lowest address register....
As per information, PCROP configuration has to be cleared on regression of RDP Level from 1 to 0. But on NUCLE-H753ZI evaluation board, PCROP configuration is not clearing on regression.But it is showing as OPTION BYTES Programming successful.Can you...
For sbsfu in the following parts:In AN5056 rev6, see section 8.5 How to validate a firmware image.In UM2262 rev8, Appendix JIt says: At the first user application start-up, if the execution is correct (for example after self-tests execution) the user...
