Hello,
I'm trying to DFU update some binaries into 1Mbyte STM32WB55CG Flash with OpenBootloader Custom APP. I've tried before with NUCLEO-WB55RG board without any problem, but with CG I just can erase/write until the first Block (512KB) of the memory. Always crashes from there.
I've checked the option bytes and FUS parameters and everything looks normal. I don't know if you have some idea why this behavior. In the post attached some captures.
I've got this contact @Alan PORTE from a colleague, but any help will be welcome. Thank you.
Sergi

Hi @domo94,
I don't think the issue is coming from STM32CubeProgrammer.
Here the CLI log from my STM32WB55CG (Nucleo-WB55 USB dongle):
Please, share a picture of the marking on your device package.
You will maybe need to go through quality.

Hi @domo94,
Thanks for the screenshots.
At first glance, I don't see anything blocking from your Option Bytes.
On my side, I did some tests with my P-Nucleo-WB55.USBDongle (which is a STM32WB55CGU6), and so far I'm not facing your issue.
If you have a P-NUCLEO-WB55.USBDongle, then it’s worth a try.
Are you facing this problem with STM32CubeProgrammer too? Or only with dfu-util?
Try to write or erase at 0x08080000 thanks to STM32CubeProgrammer.
Below dfu-util log of download test (not OpenBL) above 0x08080000:
In order to be fully aligned on the setup, please consider to share your code.

Something interesting. When programming through CLI. uC info is wrong:
Says that CG has 512KB of NVM when it has 1MB:
