What's the best way to do a software-controlled CPU reset?
Is there a quick and easy way to do a software reset on the RZ?Or is simply branching to the reset handler the appropriate way to do this?(I'm working on code that will download a new code image into...

Thanks. I got that working fairly easily - but now I'm having trouble clearing the WOVF bit at startup. I've gone over the user manual and think I'm following all the proper steps - but I end up in...

One other thing I noticed is that u-boot uses the bank command as well. So, if you do a read of an address above 16MB (sf read xxx) , it sets the bank register which might screw things up when you boot...

According to section 12.5.5 of the User's manual, the WOVF bit is NOT cleared when a watchdog reset occurs. Thus, it needs to be cleared manually - or else a subsequent watchdog reset will not occur.I...

oops, you're right. sorry (was getting confused with another SoC).That bit stays set so SW can know a WDT occurred.Well, I can say that the reset code above is the only code in the BSP that writes to...

Actually, no. According to the user manual, reads from the WRCSR register must be done as 8-bit reads. Even the Linux code does this. (I had to create the "WRCSR_R" macro myself - since the .h files...

Please note that the instructions specify to leave J11 "OPEN", but the picture shows it jumpered. I've tried both ways and neither seem to make a difference.

You want to leave J11 open, otherwise the RZ board will back feed 5 volts to the host PC on the VBUS pin. Remember, gadgets are not supposed to be driving the VCC line in a USB connector.After you plug...
