Hi,Many thanks for the experimental incremental flash feature! For me it speeds up the dev cycle considerably. (Note https://wiki.st.com/stm32mcu/wiki/STM32CubeProgrammer_errata_2.21.x seems to be broken.)Dan
Hello,I am trying to test the sbsfu project which is provided on this link. and I am using Unit Nucleo-F413ZH.I am following all the instructions step by step but on STM32Cubeprogrammer after opening file "SBSFU.elf", downloading it and then reading ...
On my computer the `stldr` files are stored like `/opt/stm32cubeprog/bin/FlashLoader/0x469.stldr` and I'm sure they exists and have correct permission. Why would it try to open the file '0x' ? Is it just a bug of string concat? Currently I cannot fla...
I have a problem with installing STM32CubeProgrammer. The installion of this program has 9 steps. However, I cannot see step 8 and step 9. For this reason, I cannot install the program. When I am looking for the solution, some people say that compute...
I am having some issues with getting UART uploading working. I can read the chip and get it's ID, but it keeps saying it cannot get acknowledgments. Everything is directly connected. Serial TX/RX to their corresponding pins and RTS to Boot and DTR t...
Hello,On STM32U575VGT with MX25L6433F over OCTOSPI1, my external loader can read successfully only once. The next read operation hangs (5-second timeout). If I disconnect/reconnect the target, the first read succeeds again, then the second read fails...
The "Discover" button on the STM32CubeProgrammer fails to connect to my my STM32H56x (STM32H562VGT6) in the Closed state (0x72). The instructions I followed for enabling password security are in the "How to enable RDP-like product state flash protect...
We have a custom loader from one of our boards. It is working in STM32 Cube MX Prog V2.16 but when I launch V2.19 and try to connect to a unrelated boards I get this error:The error is understandable because the path to the loaders is incorrect. Th...
