I have used sysgen to build a model with
microblaze, but i don't know thedifference between the two functions: microblaze_nbwrite_datafsl andmicroblaze_bwrite_datafsl. Will the later function stop the microblazeuntil finishing writing operation? thanks.
moreover, can i debug my c source code of microblaze in sysgen? if so,how?

microblaze_nbwrite_datafsl = non blocking write
microblaze_bwrite_datafsl = blocking write

On a non-blocking write the processor sets the control bit if the fsl
bus is full. On a blocking write the processor waits until the FSL bus
has space. More details can be obtained from the documentation (look
for the put instruction and its variants).
