Need Assistance

Hi all,

I accidentally erase the eeprom through the robot terminal. Once I re-download my code to the CM-5, no reaction at all from the servo. Anyone has the same experience or anyone can direct me to the previous postage related to this matter?
Thank you in advance.

Cheers,

Ryan

You probably need to tell the bootloader to run your application automatically.

If I am correct you'll find that when you switch your robot on it'll be in the bootloader (without needing to press #). You can ask the bootloader to run the application on every power on by pressing a .

Thanks for the reply.
yap you are absolutely correct. I just need to press button MODE to run the bootloader. If it functions normally, how to recognize whether the charging of the battery is in progress or it is full.. (no blinking led anymore) and when I want to change the ID for one servo, i cant use , the normal procedure in changing IDs, in page 108 from the Bioloid User's Guide.
Any idea?

Thanks again.

Cheers,

I think that the battery charging led flashing (and servo renumbering) is done in the application rather than the bootloader.

You can tell the bootloader to run the firmware by pressing 'g' - i suspect that'll bring everything to life.

On power-on the bootloader is the first thing that runs, When it runs, the first thing it does is check the eeprom to see if it should run the firmware (a.k.a. application). Assuming it's going to run the application it then waits for 1/60th of a second and then checks if you have sent a '#' down the serial (PC) link - if haven't then it'll start the application. Otherwise it'll display a prompt.

At the bootloader prompt you can use the 'a' and 's' commands to tell the bootloader to (or not to) start the application on power-on. After you have sent the 'a' command - you'll probably want to use the 'g' command to start the application now (otherwise you'll have to power cycle the CM5).

Thanks a lot. Hopefully pressing 'g' will bring everything back.

Hi,

I have tried but seems the same. I dont need to press # to go to the boot loader, once I press Mode button and the robot terminal is in boot loader mode, no need other buttons (normal condition, we need to press Mode and Start with Shift and # to go to bootloader)

Any idea?
Thanks in advance

(normal condition, we need to press Mode and Start with Shift and # to go to bootloader)

Isn't the normal condition: pressing the red button (the reset button) while sending a '#' gets you into the bootloader? (i.e. i think the start button and shift* are unnecessary)

* on my keyboard at least

I still think that you haven't put the bootloader into what it calls application mode. when you are in the bootloader try typing "help" and pressing return.

As it happens I've recently put the robotis bootloader back on my CM5 - and as a result now have recent experience of it. The command you want is "app" return - not "a" as I thought.
