[ts-7000] /dev/random blocks forever

["Emerick Rogul" <>]

Hello,

I'm implementing a cryptographic algorithm on a TS-7200 board and I need to 
produce a rather large random value to seed my random number generator (a 
minimum of 1024 bits of random data).  I was planning to read from /dev/random, 
but it blocks forever - I'm guessing because 
/proc/sys/kernel/random/entropy_avail contains no data.

Should I expect /dev/random to work (if so, how do I get the board to produce 
more entropy)?  Or should I just use /dev/urandom instead (which seems to work, 
but is supposedly not as cryptographically random)?

Thanks in advance for any help with this,

-Emerick Rogul
