Hi,

I am trying to upgrade my OSTC Mk2 from it's current v1.60 to the latest firmware.

I have followed the (Firmware update: How to) process on the sticky on this forum. I am at the point where I have the OSTC connected to my laptop, I have the V1 of the booloader opened.

• Where do I find the required .Hex file?
• How do I then use the bootloader to locate the .hex file and upload it to the OSTC?

Thanks in advance for for any help and assistance.

Inside the zip package here: http://www.heinrichsweikamp.com/en/ostc_2n/firmware/ (The zip file is called mk2_v201.zip)

Unpack the zip and locate the .HEX with "Browse".

-> Continue here:

- Choose correct COM-Port in the bootloader (The bootloader searches all COM-Ports automatically)
- In the OSTC Mk.2 Reset Menu, choose "Reboot OSTC" and confirm
- Click "write" at the bootloader within 10 seconds
- Wait about 1min.
- Don't panic if you have a "Please Wait" after the successful update for about 9 minutes...

Thanks Matthias,

I have followed the process. I am up to the point of "re-booting" and clicking "write" on the bootloader. There were 4 COM ports showing on the drop down menu.

I have pasted below the text from the bootloader....

I then had "Building MD2 Hash Please Wait" on the OSTC screen, but the unit is still on v1.60.

Hi,

when you have the list of COM-ports open and you unplug and plug-in the OSTC then the port you have to use will disappear and show simultaniously on this list.

To upgrade from 1.6 you need the older bootloader V1 i believe.

If is says 115200, then you are using Bootloader v2.

Your OSTC (still running pre-1.90 firmware) is currently only compatible with bootloader v1. And will need a reset to start loading the firmware, as described by Matthias above.

See that post too.
Best regards,

Thanks all for your continued assistance.

I believe I am using BootloaderV1....

I have followed Matthias instructions. When I click on "write" on the bootloader after selecting reboot from the OSTC menu, this is still the response on the bootloader.....

Hi,

115200 is wrong, maybe you have a corrupted tinybld.ini or no tinybld.ini at all. Please copy the attached tinybld.ini into the folder you have extracted "tinybldWin.exe" to.

Matthias,

Success! Thank you for your assistance.
