clpru: QBBS Invalid instruction

[Mark A. Yoder]

I'm use clpru to assemble some code[1] for the PRU.  Unfortunately I'm getting the following error:

QBBS A_CHANGED, r0.t0

"pru0-encoder.asm", ERROR! at line 103: [E0003] Invalid instruction
QBBS A_CHANGED, r0.t0

I can't figure out what is invalid about QBBS?  

I'm running on a BeagleBone with version 2.1.2 of clpru.

Hi Mark,

Try specifying the bit number there

QBBS A_CHANGED, r0, 0
