Hello. I'm trying to generate a ECC keypair (NIST-P256) on #SE050C. But I get an error
I've tried using ssscli
$ ssscli generate ecc 0x7777 NIST_P256
Generating ECC Key Pair at KeyID = 0x00007777, curvetype=NIST_P256

I've augmented 'i2c_a7.c' to print I2C traffic and got the following (i2c messages in cursive):

ERROR! Could not generate ECC Key Pair at KeyID 0x00007777
It looks like after sending the following command over I2C, SE050 stops responding on I2C bus.
5A 00 0E 80 81 61 00 09 41 04 00 00 77 77 42 01 03 5C 5E
The SE050 stops responding to reads from I2C.
