Trying to upgrade from V1.9 to V2.01 using bootloader 1 am and getting the following error:
Could not connect to at 19200

Any ideas ?

(Windows 7 by the way)

Thanks

Port not set. Check the Windows-Device manager for the correct COM port number. Enter this number, e.g. "COM3" into the "Comm" field.

Make sure to follow these instructions step-by-step: http://www.heinrichsweikamp.com/read.php?2,4071

Hi Matthias.

I have Coms 1,2, & 4 available for selection, but all give me a:

Connected to \\.\COM1 at 115200
Searching for PIC ..., Not found
ERROR!

Any ideas ?

Thanks

Lee

Most likely three issues here:

1. You need to find out which port is the right one:
- Unplug OSTC
- Open the device manager, expand COM port section.
- Connect OSTC -> A new port should be visible. THIS port is the right one.

2. Now you have "115200" - which means you're using the v2 bootloader. This will only work if you have 1.90 or later.

3. If you have v1 -> you need to follow the instructions correctly. Most likely you're missing the "Reboot OSTC" section here...

Hi Matthias,

Again, thanks for your reply.

With bootloader V1 I am getting somewhere in that the process appeared to be working. But I have been stuck on an orange 'please wait' screen with both blue and red blinking LED's for about 15 minutes.

Is it safe to unplug or have I frozen ?

Lee

Panic over. The 'please wait' lasted about 17 mins.

Matthias, thank you for your help and assistance.

Lee

The logbook conversion - With the "Please Wait" - always causes some panic Btw., it is safe to disconnect USB when "Bootloader" disappears.

I will need to opgrade from ver 1.7

From what I understand I need to first upgrade to ver1.8, where is this avelible for download?

Second, I will be able to upgrade directly from ver 1.8 to ver2.01 by using Botloader V2.

Jan

No, upgrade using Bootloader V2 is only possible from V1.9 upwards. Bootloader V1 should work directly from V1.7 to V2.01.

Correct, you can go in one step to the 2.01 with the v1 bootloader.

Matthias

Great, I will give it a go

I did the following:
-Installed bootloader V1
-Downloaded HEX file ver 2.01 to lockal directory
-Choose HEX file ver 2.01 in the bootloader file dialog: "Browse"
-Choose COM-Port 3 in the bootloader
-OSTC Mk.2 Reset Menu, choose "Reboot OSTC"
-Pressed "write" at the bootloader

OSTC returned to surface screen within 3 sec. and the following error apared in the Bootloader.

"Connected to \\.\COM3 at 115200
could not understand HEX file
ERROR!"

Please advice

Are you sure you selected the HEX file - and not the .zip archive?

Regards,
Matthias

Hi Matthias, you are correct.
Now new error

Connected to \\.\COM3 at 115200
HEX: 0 min old, INHX32,18Fcode+cfg, total=81556 bytes.

ERROR!

Nope, still no go.. the OSTC screen says

Buliding MD2 harse
Please wait....

Then black screen and orange led blinking only

-> Normal after every reboot - no matter if a new firmware was installed or not.

> Then black screen and orange led blinking only

-> Normal sleep mode (Charging)

The "115200" indicates your using the v2 bootloader. You need the v1 (Screenshot attached)!

Hi Matthias
From what I'm understand I use Bootloader V1.9.5
But when checking PIC I got error, see attach

When checking my PC for correct com, OSTC is com9, in the Bootloader I can only choose form com1-4.

Is there a way around this?
