Hello,

I wish to debug the provided sample project for the Pico board. I see on the Wiki page that the a JLink HW v11 is required to debug the board. I have a JLink EDU v10.1 that I bought a few years ago. I can see that it supports SWD. Will I be able to use it as well or do the HW v11 boards have some significant improvements? I am unable to find any sellers who have stock of the EDU or EDU Mini. Am I eligible as a hobbyist to buy one or do I have to be a student?

Regards,

Hi,

thanks for the reply. I can confirm that the debugging went very smoothly with the 10.1 hardware version.

I am now trying to figure out what clock rate my Pico is running at. A simple pin toggle generates a clock of around 300 kHz. One half of the wave takes around 7 assembly instructions so I am placing the clock around 4 MHz. Is that correct? How can I set the desired clock rate in the Segger Blinky project for example?

Hi, it seems that the code is being executed from the Flash which makes it so slow. I am using the SRAM example now but am noticing no speed improvements. Are there any settings for the SRAM examples?

Ok, I have figured out what was wrong. In the provided examples, the MCU is not configured to run from XOSC. As a result, it is powered by the slower and less accurate ROSC which leads to the above mentioned performance hit. I don't know if I am allowed to post links here but maybe someone can add that functionality to the provided examples to enable running the RP2040 / Pico at higher clock rates.
