<lvrp16> LongChair: some of the software DDR4 parameters are still getting worked on by Rockchip.
<LongChair> lvrp16 : what kind of parameter is that ?
<LongChair> i kind of don't understand what makes DDR4 different than DDR3 in terms of sw :)
<lvrp16> the DDR4 tuning
<lvrp16> timing tuning

<LongChair> lvrp16: well we don't have that part right yet. Do you have a dts that would work good with ddr4 ?
<lvrp16> i will send you it when i get it

<Pix> hi guys, i'm trying to flash my new sapphire rk3399, i built everything like it should ( toolchain in buildroot, uboot, kernel)
<Pix> and i'd like to begin to flash
<Pix> but..
<Pix> [root@manticore rockchip]# rkbin/tools/rkdeveloptool td
<Pix> Test Device OK.
<Pix> [root@manticore rockchip]# rkbin/tools/rkdeveloptool db out/u-boot/rk3399_loader_v1.08.106.bin
<Pix> The device does not support this operation!
<Pix> i can execute all read functions
<Pix> but none of the write ones
<Pix> (using directly rkdeveloptool, or build/flash_tool.sh)
<Pix> i'm running a fedora host, 64 bit
<Pix> am i missing something ?
<beeble> Pix: use the loader from the rkbin repo to db (this loads the flash tool) then use ul with your build bootloader
<Pix> beeble, that's exaclty what i'm doing
<Pix> see the path of rkdeveloptool in my paste just up there
<Pix> rkbin is a git clone of the github rockchip
<beeble> ok
<Pix> i have no error in the dmesg of my host linux
<beeble> and you are in maskrom mode?
<Pix> and the device has the pre-db ids: Bus 001 Device 030: ID 2207:330c
<Pix> that's the mode i'm not sure about, i only have the sapphire board, not the excavator one ( which has a maskrom button if i read well)
<Pix> i just press "recovery", and power on
<Pix> and have the bootloader output "rockusb key pressed." on the serial console
<beeble> thats rockusb mode
<Pix> ok, it's a different one..
<beeble> thats already in rockchips uboot
<beeble> yes
<beeble> in that case you should be able to just use ul of your build uboot
<Pix> ah, nice
<beeble> you only need rk3399_loader_v1.08.106.bin if there is no software at all
<Pix> i need to update uboot, the pre-flashed one have zero timeout to enter console, and i can't stop it from booting android
<Pix> ok, i understand :)
<beeble> but you may want to check how to get into maskrom as this will be your recovery methode if something goes wrong with the upgrade
<beeble> let me check the board for a sec
<Pix> well i remember reading somewhere that i could do it on the sapphire, using the windows tool (impossible under linux)
<Pix> but you're right
<Pix> would be unfortunate to brick the shiny new board
<beeble> next to the pin header
<beeble> there should be a maskrom button
<Pix> hmm
<beeble> press it while reset or powering up
<beeble> then it will be in maskrom mode and you can load the loader bin with db
<Pix> i see
<Pix> but the button is on the excavator board
<Pix> i only use...
<Pix> the "core" sapphire board
<beeble> yes
<Pix> which has power/reset/recovery
<Pix> oh fuck
<Pix> saw it!
<Pix> up left
<beeble> right :)
<Pix> ah great
<Pix> because i just flashed uboot
<Pix> and i bricked it
<beeble> all the button does is preventing the emmc to work correctly. so the soc will not be able to fetch data from the emmc and fall back into the maskrom usb mode
<beeble> so this will always work
<Pix> i see
<beeble> and then you load the rk3399_loader_v1.08.106.bin which initializes the dram and load the usbplug binary into dram
<beeble> that offers rockusb features
<Pix> aaah you thank you SO much
<Pix> i'm in uboot :)
<Pix> side note: i had to unplug the usb-c port between each flash ( idbloader, uboot and trust) because it was powering the board even with on/off switched to off, preventing it to restart each time in maskrom mode
<Pix> anyway
<Pix> thank you again
<Pix> :)
<beeble> you are welcome

<alyssa_> gah, just when I get comfy with a RK3288 machine, I start salivating over the specs of the RK3399 :V ;p
<BenG83> :)
<BenG83> I hope OrangePi's or Pine64's boards that should come out this year will drive the price further down for those SBCs
<BenG83> I wonder how meltdown/spectre mitigation fixes will impact typical usecases for RK3399

<vagrantc> only two of the 6 cores are affected ... just turn off the A72 cores :)
