How/why do you expect people here being able to answer this question?2ndSeb wrote:How do the NanoPC-T4 and the RockPro64 people do that? Is DDR vs LPDDR the big difference?
If you look at the flood of new RK3399 designs above viewtopic.php?f=149&t=31277&start=100#p230663 they all rely on LPDDR3 or LPDDR4 while the older ones (Firefly or https://www.theobroma-systems.com/rk3399-q7/overview ) use DDR3. What has happened? Maybe Rockchip provided in the past only a reference design with DDR3, then switched to a more recent one using LPDDR? And maybe Hardkernel simply started too early? Who knows? Who will tell?
You know that these boards all follow pretty closely SoC vendor's reference designs?
According to the Libre Computer guy redesigning a PCB takes 3 months at least and even then Hardkernel would've only 'yet another RK3399 thingy' and not as in the past a platform they own. All that's needed to make one board work with the OS images from another board using the same SoC is exchanging bootloader stuff (most of the times some BLOB doing DRAM initialization and controlling cpufreq/DVFS scaling, with some SoC families other than those HK uses there exist open source solutions) and DT (device-tree).
My NanoPC-T4 runs with 'Firefly kernel' and some DT adjustments (see above). No board vendor support needed at all. Once the SoC is supported by SoC vendor and there's a community around the SoC board makers can not use their own quality of software and support to differentiate their products from competitors any more.
If this vendor community here would generate some great OS images for an RK3399 based ODROID they would be 'ported' to any other RK3399 device within days if not hours.
And then customers are not able to compare prices. They do not get that HK need to have higher prices due to some extra margins their distribution channels need, they do not get that shipping costs, customs and VAT are part of the price they eventually pay but will instead simply compare list prices in online shops. How could an N1 at +100 bucks compete with a RockPro64 with same amount but faster DRAM and same config ($80 + $10 for the ASM1061 SATA card)? Same with NanoPC T4, they currently offer the 4GB version for 110 bucks with a great Wi-Fi chip and the same 16 GB eMMC on board HK sells separately as orange module.
