Logitech’s handheld plans are on ice — don’t expect a G Cloud 2 soon
Logitech's new gaming boss, Robin Piispanen, tells me he likes the idea of gaming handhelds. "It's such a charming value proposition," he says, as we sip iced vanilla lattes at my local cafe. But he's not building one right now. He's not sure when or if Logitech should try again, after its underwhelming experiment with […]

How to Apply PCB Design Standards for Better Product Design
Nothing is more frustrating than spending hours, or even days, perfecting a PCB design only to discover it fails during production. The secret to avoiding this is simple: apply PCB design standards from the very beginning. These guidelines act as a blueprint for reliability, manufacturability, and long-term performance, guiding every aspect of your board—from trace widths and spacing to via placement, solder mask, and layer stackups. Following these recommended practices doesn’t just prevent manufacturing errors—you save time, reduce costs, improve quality, and minimize delays. Whether you’re building a prototype or preparing for full-scale production, designing with these rules in mind ensures your PCB performs exactly as intended. Applying these best practices sets the foundation for success in any production scenario. By starting with the right standards, you can avoid costly mistakes before they happen and bring your product to life smoothly. Why PCB Design Standards Matter (More Than You Think) PCB standards are not theoretical rules. They are: • Proven engineering practices • Built from real-world failures • Designed to reduce risk Without them, you are basically designing blindly. With them, you get: • Higher first-pass success rate • Faster manufacturing approval • Reduced rework and cost • Better product reliability Steps to Apply PCB Standards in Your Design Here’s a practical, step-by-step guide to apply PCB design standards effectively: Step 1: Start with the Right Standards (Not All Are Needed) You don’t need to follow everything. You need to follow the right ones. Key standards to consider: • IPC-2221 → General PCB design standard • IPC-7351 → Footprint design guidelines • IPC-A-600 → PCB acceptability • IPC-A-610 → Assembly quality Practical Tip: Start with IPC-2221 + IPC-7351 if you're doing design. Step 2: Apply Standards During Component Placement Most failures start here—not routing. Common Mistakes: • Random component placement • Ignoring signal

How to debug why your PCIe device doesn't enumerate during bring up
Notes from bringing up a PCIe WiFi module on i.MX8MQ; symptoms and how to diagnose them. Phy link never came up — what does this mean? This message is typically seen in dmesg as shown below. [ 3.828121] imx6q-pcie 33800000.pcie: iATU: unroll T, 4 ob, 4 ib, align 64K, limit 4G [ 4.807241] imx6q-pcie 33c00000.pcie: Phy link never came up [ 4.841482] imx6q-pcie 33800000.pcie: Phy link never came up [ 5.821279] imx6q-pcie 33c00000.pcie: Phy link never came up [ 5.830481] imx6q-pcie 33c00000.pcie: PCI host bridge to bus 0001:00 [ 5.854997] imx6q-pcie 33800000.pcie: Phy link never came up [ 5.862205] imx6q-pcie 33800000.pcie: PCI host bridge to bus 0000:00 It means one of the following The PCIe peripheral is not powered up. PCIe reset is not deasserted, so the chip is in reset. This could be because the DTB is deasserting an incorrect GPIO. Reference clock is not enabled Using the incorrect PCIe controller in the device tree. As we can see that both the PCIe controllers can report this. So first determine which controller is the peripheral hooked to. More on this in the next section. Which PCIe controller is my device on? ( &pcie0 vs &pcie1 ) The rule here is to match by address and not by label/name. If the schematic calls out controllers as PCIE1 and PCIE2, and the device tree lists pcie0 and pcie1, understand the mapping. The DTS label is arbitrary - match by register base ( @address in the node name), which is the same in the DTS reg and the reference memory map. For definitive addresses look in the .dtsi , as sometimes the manuals are misleading. Given below is a mapping table for i.MX8MQ DTS. | ADDRESS (in .dtsi) | Silicon (RM) Label &pcie0 | 0x33800000 | PCIe1 &pcie1 | 0x33c00000 | PCIe2 The addresses are listed in the chip’s memory layout are from processor reference manual.
