    martinayotte got a reaction from Werner in Orange pi 3 - change i2c speed   
    I2C standard clock are usually 100KHz or 400KHz, but you can try other values.
    Here is the doc, the parameter is "clock-frequency" :

    martinayotte got a reaction from jsorocil in Rock PI 4 A not starting   
    No ! Not true ! Trust me, or as Igor said, read the Rockchip datasheets !
    All RK3399, as well as any other Rockchip SoC, are loading U-Boot from eMMC first.
    The fact that some boards is looking at SDCard is simply that this U-Boot loaded from eMMC is checking for SDCard with specific format, partitions, or uEnv.ini, and then continue boot process from SDCard.

    martinayotte got a reaction from gounthar in Orange Pi Zero PA19 goes HIGH when reading input   
    Pretty normal : PA19 is shared also as TWI1-SDA which is an I2C bus provided on header, and there are some PullUps resistors already present on the OPiZero board.
     
    So, simply short PA19 to GND, you will see that your script will print "0".

    martinayotte got a reaction from Jens Bauer in EspressoBin: Possible bug in boot.cmd   
    Looking at my OPiOne+, it has different addresses for "script_addr" and "load_addr" and during u-boot init it shows :
    ## Executing script at 4fc00000 ... ## Executing script at 44000000 EDIT : ... and here is what is shown for OrangePi-RK3399 :
    ## Executing script at 00500000 ... ## Executing script at 09000000

    That is maybe specific to EspressoBin, because on my Rockchip and Allwinner boards, it is as the following :
    if test -e ${devtype} ${devnum} ${prefix}armbianEnv.txt; then load ${devtype} ${devnum} ${load_addr} ${prefix}armbianEnv.txt env import -t ${load_addr} ${filesize} fi Where "load_addr" varies depend of the SoC ...

    martinayotte got a reaction from JrRockeTer in Nanopc M4V2 - reflash eMMC   
    Rockchip SoCs always have eMMC as boot priority.
    So, to boot from SDCard, you need to stop U-Boot from eMMC by pressing <spacebar> several times during startup.
    Then, at U-Boot command line, you can type "setenv devnum 1" followed with "run mmc_boot", it will then boot from SD.

    martinayotte got a reaction from jiko in Nanopi m4v2, SD reader dead, forgotten eMMC password - can I reset?   
    On all Rockchip SoCs, eMMC has boot priority over SDCard.
    If you wish to boot from SDCard, you need to stop U-Boot from eMMC by pressing <spacebar> multiple during early boot process, then you get into U-Boot command prompt.
    You can then tell U-Boot you wish to boot from SDCard by giving the "setenv devnum 1" command followed by "run mmc_boot" ...
