FlashPro-ARM/GangPro-ARM programmers support the ability to read the SFI chip certificate and save it to a file on disk.
Read The read and save chip certificate to file feature is possible also accessible by using the API-DLL.
F_ReadSTM32Certificate
General Description
Read device certificate from connected devices to FlashPro-ARM/GangPro-ARM programmers and save to file(cert_1.bin, cert_2.bin etc.)
...
STM32U5 Series
STM32L5 Series
STM32H5 Series
Syntax
| Code Block |
|---|
INT X F_ReadSTM32Certificate( char* path ); |
Input
char *path : path to save certificate file
““: save in execute place
Output
INT_X : result of operation
1 - success
2 - selected not supported vendor or family
3 - target not opened(no connection established)
4 - can’t create file or path don't exists
5 - error during read certificate
