Raspberry Pi Pico Update

Raspberry Pi Pico Update

Overview

There is an onboard RP2040 chip (pi pico). It is not present on the Jr2. It's responsible for the following things:

• the bootloader procedure that loads the right core while booting the K2.
• it is also known as the "FPGA Manager"
• Contains the K2 LCD screen special bitmap to be shown at bootup
• Has modifiably code that can invite more features and possibly a faster bootup

Finding the right header and connecting a cable

Here are the steps to follow:

• Find the right .uf2 file from this github repo https://github.com/wildbitscomputing/fpga-manager
• Find the red circled header for USB
• Use the provided USBA to female dupont connector cable you should have received with your K2 kit upon purchase. These fairly standard cables can be found online if it needs to be replaced
• While the K2 is powered off, hold the BOOTSEL button nearby and plug the cable into your modern computer
• When a special drive pops up on your modern computer, drag and drop the .uf2 replacement image for the pico into that drive - it will auto-dismount and perform the update.
