STM32H723VGT6 chip cannot erase and upload programs

[XYN]

Hello everyone,

Using the STM32H723VGT6 chip, the program can be downloaded and run normally, but cannot be erased and uploaded, prompting "Error while determining flash info (Bank 1 @ 0x90000000) Failed to read back".

The same phenomenon occurs when trying multiple new chips, including erasing when the program is not downloaded, and the same error is reported.

Please check out the pictures for guidance!

Dear @XYN ,

you need to check the version of J-flash from Segger and upgrade to newer one :

https://www.segger.com/products/debug-probes/j-link/tools/j-flash/about-j-flash/

You can see the internal Flash memory is located at 0x0800_0000 . Address 0x90000000 is for external serial memory and the flasher should know the exact reference to select the right programming algorithm.

Hope it helps you ,
