Easily work around components shortage with WIN SOURCE (Sponsored)

WIN SOURCE components supplier

The electronics industry and the severe shortage of components have had a huge impact on the electronics sector, disrupting the way products are produced and how they are produced. Despite the dramatic reduction in supply, demand for many components has increased dramatically. The reasons for the shortage of components are mainly multifaceted with the outbreak of COVID, and the aggressive stockpiling of goods by companies, and manufacturers that must prepare to shut down component production lines with lower profit margins. This has led to a narrowing of component selection, a reduction in the supply of some components, and so on. There are mainly two solutions to work around components shortage: find replaceable components or reliable component suppliers. This is where WIN SOURCE can help. The company has been assisting customers in finding deprecated, EoL (end-of-life), and difficult-to-find electronic parts ever since it was established in 1999 from its base in Shenzhen. WIN SOURCE has expanded since then with additional […]

Libre Computer ROC-RK3328-CC now supports Ubuntu 22.04 with Linux 5.18.2

Libre Computer Ubuntu 22.04

Libre Computer’s latest Ubuntu 22.04 desktop and server images for ROC-RK3328-CC board are based on Linux mainline, namely Linux 5.18.2, and other boards from the company, based on Allwinner H2+/H5 processor or Amlogic S905X, have gotten the same treatment. Some companies will churn out boards regularly but provide limited software support. Libre Computer seems to have taken a different approach, as they released most of their board in 2017 and 2018, starting with AML-S905X-CC “Le Potato” board based on the Amlogic S905X processor, followed by ALL-H3-CC “Tritium” SBC with Allwinner H2+, H3, or H5 processor, and finally ROC-RK3328-CC “Renegade” board, but still release updated OS images in 2022. I reviewed ROC-RK3328-CC SBC with Debian 9 and Ubuntu 18.04 using Linux 4.4 in July 2018, and four years later, you might have thought such boards could have become abandonware, but Libre Computer just released Ubuntu 22.04 Desktop and Server image with […]

What is PVTM? Or why your Rockchip RK3588 CPU may not reach 2.4 GHz

Rockchip PVTM

While the Rockchip RK3588 processor is advertised as reaching 2.4 GHz, not all RK3588 chips may achieve this frequency. The keyword is PVTM (Process-Voltage-Temperature Monitor), and we’ll try to explain why it does, and why some of the RK3588 processors may only be clocked at about 2.3 GHz, while others will run fine at 2.4 GHz. This all started with Rock 5B SBC debug party, where we noticed our boards did not reach the same frequency. Willy Tarreau noted the “pvtm” value was different between our boards: Willy’s board: (Cortex-A76 cluster 1 @ 2,304 MHz, cluster 2 @ 2,352 MHz)

CNXSoft board (Cortex-A76 cluster 1 @ 2,304 MHz, cluster 2 @ 2,304 MHz) :

Thomas Kaiser (tkaiser) board: (Cortex-A76 cluster 1 @ 2,400 MHz, cluster 2 @ 2,400 MHz)

For reference, CPU 0 to 3 are Cortex-A55 cores, CPU 4-5 are two Cortex-A76 cores (cluster 1), and […]
