Is that speed will be the same for Olinuxino A20 Lime2 board? it is too slow for SSD disk which is attached on SATA port.I expected much more, but I see in Youtube some guys showing speed transfer results on Raspberry Pi 4 and Rock Pi4 with attached SSDs on their USB 3.0 ports and the results are something like 260 Mb/s for read and 245Mb/s for write, which can be acceptable as good performance.

Hello guys and gals Can anyone help me what information to add in boot.cmd file to make it bootable from SSD on SATA port? I found some examples but they are from 2014 and the information in my boot.cmd file looks slightly different from what is posted in the past. I'm using the latest Buster Server image with 4.19 kernel. By the way is it a good idea to enable TRIM for the SSD? I saw some options in YouTube how to enable TRIM, but just want to ask for opinion of people with SSD drives, who already managed to boot from SATA with SSD. setenv load_addr "0x44000000" setenv overlay_error "false" # default values setenv verbosity "1" setenv console "both" setenv disp_mem_reserves "off" setenv disp_mode "1920x1080p60" setenv rootfstype "ext4" setenv docker_optimizations "on" setenv rootdev "UUID=356XXXX-XXX-XXXX-XXXX-XXXXXXXXXX" # Print boot source itest.b *0x28 == 0x00 && echo "U-boot loaded from SD" itest.b *0x28 == 0x02 && echo "U-boot loaded from eMMC or secondary SD" itest.b *0x28 == 0x03 && echo "U-boot loaded from SPI" # get PARTUUID of first partition on SD/eMMC it was loaded from # mmc 0 is always mapped to device u-boot (2016.09+) was loaded from if test "${devtype}" = "mmc"; then part uuid mmc ${devnum}:1 partuuid; setenv devnum ${mmc_bootdev} setenv rootdev "/dev/sda${mmc_bootdev}p1" fi echo "Boot script loaded from ${devtype}" if test -e ${devtype} ${devnum} ${prefix}armbianEnv.txt; then load ${devtype} ${devnum} ${load_addr} ${prefix}armbianEnv.txt env import -t ${load_addr} ${filesize} fi if test "${logo}" = "disabled"; then setenv logo "logo.nologo"; fi if test "${console}" = "display" || test "${console}" = "both"; then setenv consoleargs "console=ttyS0,115200 console=tty1"; fi if test "${console}" = "serial"; then setenv consoleargs "console=ttyS0,115200"; fi setenv bootargs "root=${rootdev} rootwait rootfstype=${rootfstype} ${consoleargs} hdmi.audio=EDID:0 disp.screen0_output_mode=${disp_mode} panic=10 consoleblank=0 loglevel=${verbosity} ubootpart=${partuuid} ubootsource=${devtype} usb-storage.quirks=${usbstoragequirks} ${extraargs} ${extraboardargs}" if test "${disp_mem_reserves}" = "off"; then setenv bootargs "${bootargs} sunxi_ve_mem_reserve=0 sunxi_g2d_mem_reserve=0 sunxi_fb_mem_reserve=16"; fi if test "${docker_optimizations}" = "on"; then setenv bootargs "${bootargs} cgroup_enable=memory swapaccount=1"; fi load ${devtype} ${devnum} ${ramdisk_addr_r} ${prefix}uInitrd load ${devtype} ${devnum} ${kernel_addr_r} ${prefix}zImage if test -e ${devtype} ${devnum} "${prefix}.next"; then echo "Found mainline kernel configuration" load ${devtype} ${devnum} ${fdt_addr_r} ${prefix}dtb/${fdtfile} fdt addr ${fdt_addr_r} fdt resize 65536 for overlay_file in ${overlays}; do if load ${devtype} ${devnum} ${load_addr} ${prefix}dtb/overlay/${overlay_prefix}-${overlay_file}.dtbo; then echo "Applying kernel provided DT overlay ${overlay_prefix}-${overlay_file}.dtbo" fdt apply ${load_addr} || setenv overlay_error "true" fi done for overlay_file in ${user_overlays}; do if load ${devtype} ${devnum} ${load_addr} ${prefix}overlay-user/${overlay_file}.dtbo; then echo "Applying user provided DT overlay ${overlay_file}.dtbo" fdt apply ${load_addr} || setenv overlay_error "true" fi done if test "${overlay_error}" = "true"; then echo "Error applying DT overlays, restoring original DT" load ${devtype} ${devnum} ${fdt_addr_r} ${prefix}dtb/${fdtfile} else if load ${devtype} ${devnum} ${load_addr} ${prefix}dtb/overlay/${overlay_prefix}-fixup.scr; then echo "Applying kernel provided DT fixup script (${overlay_prefix}-fixup.scr)" source ${load_addr} fi if test -e ${devtype} ${devnum} ${prefix}fixup.scr; then load ${devtype} ${devnum} ${load_addr} ${prefix}fixup.scr echo "Applying user provided fixup script (fixup.scr)" source ${load_addr} fi fi bootz ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r} else echo "Found legacy kernel configuration" load ${devtype} ${devnum} ${fdt_addr_r} ${prefix}script.bin bootz ${kernel_addr_r} ${ramdisk_addr_r} fi
