Title: MAC OS Settings
Post by: gjimenez on August 05, 2015, 06:08:22 PM

I am trying to Firmware flash a device (a calculator) connected to my Mac Mini (OS Yosemite), on a USB port, but I am not being able to connect to this device

I don't know what COM Port to use, or what baud rate

Thank you for your help !

Please start a new topic for new questions. I've fixed it for you this time.

What microcontroller is being used?

Thank you Andy. The CPU on the "device" (a calculator) is the LPC1115

Start off with 19200 baud, which is slow but should be reliable.

For the COM port please carefully read through this:

Hello Andy,

This is what I see in terms of available COM ports:

lrwxr-xr-x 1 gjimenezdorigo admin 23 Aug 7 15:32 COM11 -> /dev/tty.EV3-SerialPort
lrwxr-xr-x 1 gjimenezdorigo admin 32 Aug 7 15:32 COM12 -> /dev/tty.GiovanniJimenezsiPod-Wi
lrwxr-xr-x 1 gjimenezdorigo admin 23 Aug 7 15:32 COM13 -> /dev/tty.SLAB_USBtoUART
lrwxr-xr-x 1 gjimenezdorigo admin 31 Aug 7 15:32 COM4 -> /dev/cu.Bluetooth-Incoming-Port
lrwxr-xr-x 1 gjimenezdorigo admin 23 Aug 7 15:32 COM5 -> /dev/cu.Bluetooth-Modem
lrwxr-xr-x 1 gjimenezdorigo admin 22 Aug 7 15:32 COM6 -> /dev/cu.EV3-SerialPort
lrwxr-xr-x 1 gjimenezdorigo admin 31 Aug 7 15:32 COM7 -> /dev/cu.GiovanniJimenezsiPod-Wi
lrwxr-xr-x 1 gjimenezdorigo admin 22 Aug 7 15:32 COM8 -> /dev/cu.SLAB_USBtoUART
lrwxr-xr-x 1 gjimenezdorigo admin 32 Aug 7 15:32 COM9 -> /dev/tty.Bluetooth-Incoming-Port

So I assume I should use either Com 8 or COM 13

When I use COM 13, I get the "Failed to Autobaud - step 1" error msg. I went to the forum page but cannot figure out what I need to do to make the connection. The calculator I am trying to connect is new, and the cable (micro USB - USB) is new as well, so I doubt the issue is with the calc or the cable

Thanks !

How are you putting the LPC1115 into ISP mode exactly?

Yes, I selected LPC1115/303

Selecting a microcontroller in Flash Magic doesn't put it into ISP mode. It is done by setting the state of specific pins on the microcontroller while resetting it. Please see the LPC1100 user manual from NXP for full details. Look at the flash programming chapter.
