compiling error after installing tpc/ip update 752

After I installed tcp/ip update 752 (with other required updates), I get the following error when compiling:

bsp/7_5/connectme9210/lib/libbsp.a(aes_openssl.o): In function aes_dma_set_encrypt_key': ./devices/ns9xxx/ns9215/aes/aes_openssl.c:70: undefined reference to private_AES_set_encrypt_key’
bsp/7_5/connectme9210/lib/libbsp.a(aes_openssl.o): In function aes_dma_set_decrypt_key': ./devices/ns9xxx/ns9215/aes/aes_openssl.c:100: undefined reference to private_AES_set_decrypt_key’
collect2: ld returned 1 exit status
make: *** [image.elf] Error 1
make: Target `all’ not remade because of errors.

Any suggestions?

you have installed BSP updates most likely, but did not update your platform folder. Please create a new DigiESP project and make sure it compiles. If it does, compare platform folders and copy over updated files merging your changes
