    Hallo @mabs, ja. Der uboot wird in den SPI Speicher geladen. Der sucht dann beim Starten nach einem bootfähigem Device. So wie auf einem ganz normalen PC. Eine richtig coole Sache, wo ich mich freue, das das langsam mal funktioniert. Die Performance wird ja dann sicherlich von dem Device bestimmt. Dazu gibt es ja genug Messungen. Ich würde eine NVMe SSD immer einer SATA Platte vorziehen. Es kommt aber auf den Anwendungsfall an. Für ein NAS dann eher zwei oder mehr SATA Platten, und von USB3 HDD booten So wie ich das schon lange betreibe. Aber, da hat auch jeder andere Vorstellungen und Vorlieben für.
  • ROCKPro64 - USB-OTG funktioniert!

    Für dies Kernal: Linux rockpro64 4.4.167-1213-rockchip-ayufan-g34ae07687fce #1 SMP Tue Jun 18 20:44:49 UTC 2019 aarch64 GNU/Linux Booten von der NVMe Platte nicht möglich. Ich folgte die folgende Schritte. Leider funktioniert es nicht. Es gibt einen Fehler in Boot. Ohne RAID oder LVM config. Specs: Rockpro64 Marvel PCIe 88se9230 karte SANDISK SSD 120 GB

The larger is the buffer, the more significant == == are relative contributions of TLB, L1/L2 cache misses and SDRAM == == accesses. For extremely large buffer sizes we are expecting to see == == page table walk with several requests to SDRAM for almost every == == memory access (though 64MiB is not nearly large enough to experience == == this effect to its fullest). == == == == Note 1: All the numbers are representing extra time, which needs to == == be added to L1 cache latency. The cycle timings for L1 cache == == latency can be usually found in the processor documentation. == == Note 2: Dual random read means that we are simultaneously performing == == two independent memory accesses at a time. In the case if == == the memory subsystem can't handle multiple outstanding == == requests, dual random read has the same timings as two == == single reads performed one after another. == ========================================================================== block size : single random read / dual random read 1024 : 0.0 ns / 0.0 ns 2048 : 0.0 ns / 0.0 ns 4096 : 0.0 ns / 0.0 ns 8192 : 0.0 ns / 0.0 ns 16384 : 0.0 ns / 0.0 ns 32768 : 0.0 ns / 0.0 ns 65536 : 4.5 ns / 7.2 ns 131072 : 6.8 ns / 9.7 ns 262144 : 9.8 ns / 12.8 ns 524288 : 11.4 ns / 14.7 ns 1048576 : 16.0 ns / 22.6 ns 2097152 : 114.0 ns / 175.3 ns 4194304 : 161.7 ns / 219.9 ns 8388608 : 190.7 ns / 241.5 ns 16777216 : 205.3 ns / 250.5 ns 33554432 : 212.9 ns / 255.5 ns 67108864 : 222.3 ns / 271.1 ns
