  1. To whom it may concern : found another not-working M.2 NVMe SSD DEM28-A28M61BWAQC PS It also equipped with Toshiba chips
  2. Thanks to everyone who replied ! It was bad luck with Toshiba . Successfully verified 3 different M.2 SSD models : Samsung 970 EVO Kingston SA1000M8 Intel SSDPEKKW128G801 All three are working just fine (as it should be) , Samsung is the fastest . Beware of Toshiba KBG30ZMS256GA !
  3. Yes, that Toshiba accidentally turned out to be the only M.2 NVMe SSD we currently have for testing. And looks like it's not a perfect fit. We ordered a couple of M.2 2280 SSDs - Samsung & Kingston , and will test with them when they will be delivered. And we constrained by time and money - don't want to waste them playing with multiple drives available on the market .. Thank you very much for your reply ! I'll update upon our results with Samsung and Kingston.
  4. Hello to everyone , We have several T4 boards and can't get the NVMe SSD we currently have - Toshiba KBG30ZMS256GA - working ... Tried different 4.4 kernels and various distros . The SSD itself proofed to be working in Mikrotik RouterBoard RBM33G . Before we buy some other NVMe SSDs to try , I want to ask for advise . Is it ok to get such messages from kernel : # dmesg | grep -i pci PCI I/O : 0xffffffbffee00000 - 0xffffffbfffe00000 ( 16 MB) [ 0.119383] PCI/MSI: /interrupt-controller@fee00000/interrupt-controller@fee20000 domain created
  5. Hello everyone, I'm trying to build a kernel so that OTG USB interface with Type-C connector could be accessed as usb0 network interface . If someone managed to solve this - please, share your experience .
  6. Thank you so much, Martin ! UART2 is found on pins 11,13 indeed ! One more question: is it right to define in armbianEnv.txt param_pps_pin=PA7 and connect PPS wire to pin 29 ? I mean no mismatch here ?
  7. Hello to everyone , I'm trying to read NMEA messages from GPS receiver via UART . But can't read anything on pins 8,10 & 38,40 .. What coulb be a reason ? GPS receiver is working fine , I can read it via USB-UART converter on the same board ... Thanks in advance ! Here's my system (UARTs are enabled via armbian config utility): root@orangepiprime:/boot# cat armbianEnv.txt verbosity=1 console=both overlay_prefix=sun50i-h5 rootdev=UUID=aca8c4ac-41d0-4e0b-ae7e-1d727baa4d43 rootfstype=ext4 overlays=pps-gpio uart1 uart2 uart3 us
