I was startled by your comment that USB to I2C (CP2112) might be NRND, but luckily it isn't. This is the only USB to I2C interface I know of that is supported by the Linux kernel. There was a CP2130 driver proposed last year, but that didn't make it into the kernel yet.

I would expect that a USB-HID to SPI might get more interest.

Hi Maarten,

The menu item is from the file 'studio.desktop' and so if setup.sh is run again it is not overwriting the existing copy of the file.  The file will be located in one of 3 places (the setup.sh script can be examined to see the logic for creating it):

1. /usr/share/applications/ - If this folder exists the studio.desktop file is placed here.

2. /home/[USERNAME]/.local/share/applications this location is checked next

3. /home/[USERNAME]/Desktop

So you can either delete the studio.desktop file and then run setup.sh again or else you can edit that file and change the path for 'Exec'.

It shows up in Other instead of Programming because the studio.desktop file does not contain a line for "Categories".  My Ubuntu installation does not show product grouping under Applications, but I think if you add this line it would show up in the Programming group:

Categories=Application;Programming;

I will create a bug report to enhance the setup.sh script.  One limitation is the current scheme does not support being able to start multiple installs of Simplicity Studio from the Applications menu.

Thank you,

Thanks,

It appears that I had two 'studio.desktop' files, one in each of the first two places you mentioned. I had already changed the path through 'Edit Menus' but it would not show the proper icon nor run when clicked. Probably due to the duplicate.

E.g. Visual Studio Code and Meld are put in the Programming group, at least on my Ubuntu Mate 20.04 LTS.

I also wonder if 'studio.desktop' is a well chosen name. I recommend to rename it to 'SimplicityStudio.desktop'.

Hello,

I downloaded Simplicity Studio v5 on Ubuntu 20.04 LTS, opened the .tgz and read the README.txt which just told me to run

sudo SimplicityStudio_v5/setup.sh

So I did, but it turned out it was just installing in-place instead of asking me where to install as I expected. This is not what I wanted, but how is one supposed to uninstall / reinstall?

I tried just removing the dir and unpack anew. But now the setup.sh script no longer creates a proper Menu item.

B.t.w. Why is Simplicity Studio in "Other" instead of "Programming" ?

I would start by sending data out of the LEUART and check if you see it on the TX pin.

Then I would try not to sleep in EM2 and see if the interrupt service routine is reached.

Beware, btw. that the LFRCO is too inaccurate for a decent UART baudrate. It is highly voltage and temperature dependent.

You may consider to implement this by yourself with python since the hex2boot and efm8load are open source.

Where can we download the sources for hex2boot?
