Getting error 0x6985 with SE05x

[ar01]

Hi,

I'm using the evaluation board for SE052. I'm trying to implement the se052_reset_example but it is not working. The function ex_sss_boot_open works fine and the applet is selected. However, the next command from Se05x_API_GetRandom function returns the error 0x6985. 

I've also tried sending different commands after ex_sss_boot_open, like Se05x_API_GetFreeMemory but I received the same 0x6985 error.

Thanks.

Hi @ar01 ,

Actually the SE052F uses like SE050F a mandated PlatformSCP connection. Did you configure the MW correctly ? Please kindly refer to https://www.nxp.com/webapp/Download?colCode=AN14028 for more details.

Hope that helps,

Have a great day,
Kan

Thanks Kan!, I thought that was disabled by default, I changed the features to include the platform scp and that worked. Have a nice day.
