Sino. Vo. IP has unveiled yet another new board with Banana Pi BPI M2 Berry this week end. Its actually quite similar to Banana Pi BPI M2 Ultra board, by they replaced Allwinner R4. Allwinner V4. 0 processor, removed some features, and use Raspberry Pi 3 form factor. If we look at Allwinner V4. Technical details. Like other embedded IP cores for 3D rendering acceleration, the Mali GPU does not include display controllers driving monitors such as the. V4. 0 potentially exposing an extra CAN bus.

BPI M2 Ultra Board with Allwinner V4. Processor. So why bother doing different processors since they are so similar Last time, we were told Allwinner A6. R1. 8 had different SDKs, so it should be the same for R4. V4. 0. Allwinner has different family of processors dedicated to different market segments A series are application processors, H series are for home entertainment, R series for the Io. T, and V Series for video camera applications. In some ways, it makes sense to have different business units that specialize in specific market segments. If you customer wants to make an action camera redirect him to the V series guys, a TV box thats for H series, and so on. Theres been a long ish discussion about Allwinner business units on CNX Software. What has apparently been happening is that some processors can be used across market segments, so they have duplicates or close to it with for example Allwinner A6. R1. 8 thats just the same chip but assigned to a different business unit. Each business unit work and release their own SDK, and based on different Linux and Android version for different SDK, there does not seem common work across business units, and they appear to have separate software teams. The processors are differentiated by CHIP ID, and by default you cant run firmware generated by R1. SDK on A6. 4, and vice versa, since the bootloader will detect the ID and prevent the software to run. That also looks like a bad idea, since for example a software bug fixed on Allwinner R1. SDK, may go unnoticed on Allwinner A6. So ideally all business units should get their software from a single team taking care of low level software bootloaderkerneldrivers, middleware Androidrootfs, while software developers part of a given business unit may work on the market specific software. Jon had more insights on this business organization The R group is releasing a different SDK for the R1. They are not using the A6. That strongly suggests to me two sets of software people. A single software group would have simply added the R1. A6. 4 SDK. You want a centralized Linux and Android group. Then inside that group you develop specialists. For example the DMA person, the UART person, the Ethernet person, etc. That person is responsible for driver support over all of the CPUs Allwinner makes. They become experts on this piece of the SOC. The output of this group is a single SDK that supports all Allwinner processors. Like what mainline Linux is doing for Allwinner SOC currently. Not the single CPU kernels that AW keeps releasing. Then you can give this central software group two instructions 1 Add a new SOC to the existing base. Euro Truck Simulator Romania. Each specialist will extend their existing driver to add support for the new SOC. Not cut and paste then edit to make a new driver That happens with separate groups. Add support for a new kernel or Android release. Everyone in the group works together to bring all of the SOC support up to this new release. This is not that hard now since each expert in their niche will know exactly what the issues are. The central group allows these vertical specialists to exist. Having the chip groups do it results in a lot of copypasteedit which we see in spades and many bugs because the work is having to be done by generalist assigned to the group. When the programmers belong to the hardware groups Allwinner is creating port and forget specialists. This awful management style was practiced by most of the US semiconductor industry in the 1. Most have discovered that it was a really bad way to do things and have reorganized. This management style occurs when chip people end up in top management at these SOC companies. They treat everything like a chip and software is definitely not a chip. But these chip heads dont know much about software so they cant see how bad this organization design is for long term support. You cant blame the chip heads for acting this way, it is the only area they have worked in. What they are doing is the correct model for making chips. Now I dont have detailed internal org charts for Allwinner. But I used to work for US companies that had this exact management structure before realizing how messed up it was. Only after a couple of very expensive failed launches of new chips because the software supporting them didnt work did management change. Another not directly related complain is that Allwinner will also release the source code as tarballs, and they dont have a git or other revision control system repository accessible to customers, for example like Amlogic or Rockchip already do. Instead they release those large tarballs, and then linux sunxi community may import the u bootLinux kernel part to github, and work on them, although those days, they may prefer to focus on mainline rather than on Allwinner SDK releases.
