I drop down the Raspberry - i need more disk performance for my project, but they didn’t do anything even in pi 3.
So, now i try to use Navio 2 with some alternative boards… it’s not working.
I check with Banana Pro, witch have the same 40-pins connector with the near-same pin map, as pi2, but Navio 2 is not even initialize correctly.
Dear emlid guys, could you please help me - what’s wrong with it? Some pin mismatch? Some raw incompatibility?
Or i need to stop this and going to other ubox-based boards, which are working with Banana?
That’s what is wrong. All Raspberry Pi clones never have a proper compatibility, which in fact is possible if they put a little bit more thought into it during the embedded design stage. There’s always something lacking - some peripheral controller, a gpio, etc.
Also, most of these clone boards usually based on chinese processors that are designed with only one goal in mind - to be used in Android phones and media boxes. They don’t care about Linux and usually provide only basic ports with most components not working or/and fully bugged until open-source enthusiasts reverse-engineer them and write proper drivers.
Let’s see about the future, but i don’t so optimistic about Pi here. They stuck, at my point of view.
Ok, We are need two things - RAW u-blox data for kinematic and IMU data or close-quarter.
This works nice for Pi 1/2 and Navio 1 board, but now we are forced to change system completely.
We are check some N2 boards - still can work with IMU, but RAW is not available - that’s why i mention M8T as a chip replacement.
However, Pi now is not enough for us now die to poor SD/USB drive performance.
I check Banana pinout - it’s quite close to Pi B+/2 - so just can’t configure out what the difference - and is it possible to solve it. Now i have only red blink/green light - but no out in SPI ports.
Sorry, we are not usual kind of the clients, we are using you boards as a all-in-one solution for sub-decimeter location & some other nice real-time tricks. I keep in mind maybe it’s not you market, but it’s pity to see you lost possibilities here.
