07:29 <beeble> lurchi_: https://memorylink.samsung.com/ecomobile/mem/ecomobile/product/productDetail.do?topMenu=A&subMenu=tablets&appNo=tablets&appLabel=Tablets&partNo=K4E6E304EE-AGCE&partSetNo=LPDDR3 i think if samsung tells you it's lpddr3 it's pretty certain it is one :)

07:30 <paulk-gagarine> via, well, I did solder on the pins directly many times, but maybe it's not the best thing to recommend, indeed ;)

09:20 <rperier> beeble: I agree, I don't think that LPDDR3 is supported. Typically, in memory_init() only DDR3 init sequence is done or timings for DDR3_1600K are computed. Which might explain the issues I have

09:56 <skjensen1> Hi guys, I'm trying to get the serial debug working on my firefly-rk3399 but all I'm getting is a single column of odd characters and symbols

09:56 <skjensen1> Anyone who got an idea what could be wrong?

10:01 <beeble> what baudrate are you using?

10:01 <skjensen1> 1500000 8N1

10:02 <skjensen1> Both hardware and software flow control are set to off

10:03 <skjensen1> I change the linewrap setting, now it's not in a single column but still not readable..

10:03 <beeble> did you use mainline or u-boot-rockchip?

10:04 <skjensen1> u-boot-rockchip

10:04 <beeble> your settings should be fine then

10:05 <skjensen1> Are the settings different for mainline?

10:05 <beeble> no, but you can change the baudrate there in a easier way (kconfig)

10:06 <skjensen1> Okay..

10:08 <beeble> i assume you are using J20 (next to the m2 connector)

10:09 <skjensen1> Sorry, I don't know what that means

10:09 <skjensen1> I connected to the 3 pin debug port

10:09 <beeble> if it's called like that ok. (i don't own that board)

10:10 <skjensen1> I followed this guide: http://wiki.t-firefly.com/index.php/Firefly-RK3399/Serial_debug/en

10:11 <beeble> so far thats all done right

10:12 <beeble> last two things i can think of. does your converter support the baudrate? so have you already used it once with the rk3399?

10:13 <skjensen1> No, but it's a PL2303 chip serial/usb converter

10:14 <beeble> second thing, maybe check if your bootloader is actually starting. connect the board with the type c cabel to your pc

10:14 <beeble> and see if it appears there as a device

10:14 <beeble> if so your bootloader is not starting and you only see garbage on the line

10:15 <skjensen1> Yes it shows up as a device

10:17 <beeble> then you didn't copy the bootloader correctly onto your boot medium

10:17 <skjensen1> Okay.. I'm going to try that part again

10:17 <BenG83> PL2303 doesnt do 1.5MBaud

10:18 <BenG83> you need PL2303HX

10:18 <BenG83> 0012C000h 1228800

10:18 <BenG83> is the max for PL2303

10:19 <skjensen1> Oh.. That will explain it

10:19 <BenG83> FT232RL also works (up to 3MBaud)

10:19 <BenG83> CH403

10:20 <BenG83> PL2393HX goes up 12MBaud

10:20 <BenG83> *2303

10:26 <skjensen1> Thanks for the help.. :) I will go shopping for a new serial device

10:30 <r1kaomsk_work__> WOW SORRY

10:30 <r1kaomsk_work__> skjensen1, https://aliexpress.com/item/5pcs-lot-Free-Shipping-FT232RL-FT232-USB-TO-TTL-5V-3-3V-Download-Cable-To-Serial/32582811976.html im using this board

10:32 <beeble> we put a CP2102N on our evk

12:06 <rperier> so, I think that rk3368-efuse is in standby... I can test it without the secure mode :/

12:06 <rperier> cannot*

13:04 <r1kaomsk_work__> where i can buy rockchip dev boards?

14:02 <rperier> mmind00: I don't know if my question makes sense, but do you know if It's possible to toggle the necessary sgrf bit from the kernel and not from the booloader (for put configurable IP to non secure mode) ?

14:02 <rperier> something local that I could try for disable this secure mode on the efuse... so I could fixe the driver and send another version

14:03 <rperier> otherwise I am currently blocked :(

14:03 <mmind00> rperier: not from the kernel ... that is most likely a switch only accessible to the secure part, so bootloader but not kernel

14:05 <rperier> eerff

14:08 <rperier> technically... I can get the code of the vendor uboot modify it for toggling this sgrf bit... flash it and test it... right ?

14:11 <beeble> i think rockchip u-boot runs in el3, but not 100% sure

14:13 <rperier> mhhhh I will give it a try

20:44 <beeble> rperier: thinking about it again, atf probably drops uboot to el2 or 1. but as an easy check just make a md in uboot on a sgrf. if it results in a abort it's nit running in el3

22:28 <lurchi_> beeble: the CP2102N is nice, programmable serial number *and* 4? GPIOs

22:29 <lurchi_> the older CP210x had either one or the other
