[08:58:28] <akshay_> Hi, Has anyone ever actually populated an Allwinner A13 here? I did and its not booting up. I need some pointers to get it to boot up.
[12:16:12] <Tsvetan> akshay read the console messages and you can see where and why it stops
[13:10:40] <kmmndr> hi all :-)
[13:11:16] <kmmndr> is anyone using an ESP8266-EVB using USB-serial-cable-F ?
[13:51:19] <Tsvetan> kmmndr yes
[14:19:35] <kmmndr> Tsvetan: what kind of tools are you using to program / flash the chip ?
[14:20:39] <kmmndr> (the USB-serial-cable-F does not have DTS/RTS which seems to be used as software reset by most esp tools)
[14:55:47] <Tsvetan> esptool
[14:56:09] <Tsvetan> press the button before power to enter in bootloader mode
[14:56:22] <Tsvetan> I believ all this is explained in the user manual
[14:57:24] <kmmndr> that's what I did ... sometimes it's working properly, sometimes it hangs during transfers
[14:59:06] <kmmndr> and the probability to hang is very high
[15:27:30] <Tsvetan> check your power supply
[15:33:01] <kmmndr> do you think I might not have enough power on the chip ?
[15:33:16] <kmmndr> same error using another one
[15:43:59] <philippe_fouquet> Hi
[15:44:46] <philippe_fouquet> I have a small problem with Olinuxino-micro 4Go and android
[15:45:10] <philippe_fouquet> some times when it boot it stop on boot0
[15:47:25] <philippe_fouquet> affter "dram size = 1024MB"
[15:48:59] <philippe_fouquet> but in loke like fail at line msg("%x\n", *(volatile int *)0x52000000)
[15:49:26] <philippe_fouquet> some body have a idea?
[16:14:16] <superguest> hello
[16:14:25] <superguest> quick question about to order a bord from ur website
[16:15:32] <superguest> https://www.olimex.com/forum/index.php?topic=2163.0
[16:16:25] <superguest> does this olimexino stm32 support stlink debugger?
[16:17:38] <Tsvetan> superguest we don't have stlink to check but if stlink supports stm32f103 should not be an problem
[16:18:15] <Tsvetan> philippe_fouquet: 99.99% of errors we have seen are due to junky power supplies users use
[16:18:24] <superguest> no
[16:18:25] <Tsvetan> check if you power supply have enough power
[16:18:33] <superguest> i dont have the board
[16:18:37] <superguest> i just need to know how to debug
[16:18:42] <Tsvetan> and if you supply power to the USB-OTG connector
[16:18:45] <superguest> @____@
[16:18:47] <Tsvetan> you shouldn't
[16:18:49] <superguest> i want
[16:18:53] <superguest> to see how the bootloader works
[16:18:56] <superguest> and other stuff
[16:18:59] <superguest> memory acces
[16:19:03] <superguest> trace every stap
[16:19:06] <superguest> wanna put a rtos on it
[16:19:10] <Tsvetan> if you have debugger you do not need bootloader
[16:19:19] <superguest> i am unfamiliar
[16:19:21] <Tsvetan> the bootloader is made to skip the programmer/debugger
[16:19:30] <superguest> o;
[16:19:34] <superguest> but
[16:19:38] <superguest> what debug can i use?
[16:19:46] <superguest> which connector do u use to it?
[16:20:00] <Tsvetan> you do not need debugger if you use Maple IDE
[16:20:09] <superguest> maple ide has build in debugger?
[16:20:12] <superguest> with step function?
[16:20:15] <Tsvetan> debug is same as in all Arduinos with serial print
[16:20:19] <superguest> no
[16:20:21] <superguest> thats not debug
[16:20:28] <superguest> i can do that with printf
[16:20:28] <Tsvetan> right
[16:20:35] <superguest> i want to do true debug
[16:20:41] <Tsvetan> this is the debugger for no money :)
[16:20:46] <superguest> i know that ;p
[16:20:51] <Tsvetan> if you want true debug you [pay for debugger and use it
[16:20:58] <superguest> but u offer a tjag for 5 euro
[16:21:15] <superguest> https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10/
[16:21:18] <superguest> jtag*
[16:21:23] <superguest> can i use this to debug the olimexino?
[16:21:53] <Tsvetan> this is not jtag just adapter board from ARM big connector to STM32-OLimexino small 0.05" step connector
[16:22:07] <superguest> so there is no debug on this wonderfull olimexino???
[16:22:11] <Tsvetan> so you need debugger + this board to connect
[16:22:19] <superguest> which debugger?
[16:22:21] <superguest> how do i connect?
[16:22:24] <Tsvetan> did you read the forum thread you mention at all?
[16:22:31] <superguest> i dont understand it omg
[16:22:49] <Tsvetan> "As of general info we manufacture two types of STM32 compatible debuggers - based on OpenOCD design recommendation (ARM-USB-TINY-H, ARM-USB-OCD-H) and based on CooCox CoLinkEx design (ARM-JTAG-COOCOX)."
[16:23:05] <Tsvetan> :)
[16:23:20] <superguest> O:
[16:23:23] <superguest> manufacture?
[16:23:29] <superguest> so its on the website?
[16:23:44] <Tsvetan> you need JTAG debugger like stlink, or ARM-USB-TINY-H or ARM-USB-OCD-H or ARM-JTAG-CooCox
[16:24:04] <Tsvetan> then you need adapter board ARM-JTAG-2010 to connect it to STM32-Olimexino
[16:24:08] <Tsvetan> is it clear now :)
[16:24:24] <Tsvetan> yes, all three you can type in the search box on our web and see
[16:24:30] <philippe_fouquet> Tsvetan: thank i check it
[16:24:39] <superguest> but
[16:24:50] <superguest> these debuggers are twice the price of the board @____@
[16:25:17] <Tsvetan> superguest then use printf
[16:25:22] <Tsvetan> if no money for debugger
[16:25:34] <superguest> why u do dis
[16:26:26] <superguest> still
[16:26:28] <superguest> i am confused
[16:26:35] <superguest> so st link is not supported
[16:26:43] <superguest> that while the chip is arm cortex m3 stm32
[16:26:51] <superguest> and i dont know which port i use
[16:27:18] <superguest> how do i make this debugger attach to the olimexino?
[16:27:49] <Tsvetan> olimexino schematic is public - just connect the correct wires from stlink to olimexino
[16:28:13] <superguest> i am looking at eagle
[16:28:14] <superguest> but i am to dumb
[16:28:45] <superguest> this board has 64 io
[16:31:15] <superguest> there are no pins named JTAG
[16:31:20] <Tsvetan> you have to connect just JTAG signals to STlink debugger all they are on the small connector
[16:32:39] <superguest> ?
[16:33:23] <superguest> can u please help me
[16:33:24] <superguest> i dont see it
[16:34:16] <superguest> omg
[16:34:17] <superguest> nvm
[16:34:26] <superguest> i found it
[16:41:29] <superguest> ok
[16:41:39] <superguest> i think if i order it from mouser i don t get shipping fee
[16:42:52] <superguest> u know the original maple board
[16:43:00] <superguest> has these traces which look so pretty
[16:43:13] <superguest> http://thatcadguy.blogspot.nl/2012/07/olimexino-stm32-maplearduino-like-arm.html
[16:43:42] <superguest> such a shame that this style isnt used in the olimexino
[16:48:29] <superguest> o my god the shipping fee is everywhere
[16:50:13] <superguest> oh farnell comes to rescue meeee ;DD
[16:50:56] <superguest> o nooo
[16:51:03] <superguest> need to order minium of 50 eurooo
[17:13:28] <superguest> o bbaby
[17:13:31] <superguest> conrad o so sexy
[17:13:39] <superguest> only needs 25+ euro and free shipping
[17:13:40] <superguest> so sexy
[17:34:26] <lanodan> Hey, does someone knows the LVDS pins ? (I'm making an olimex LCD→LVDS)
[17:38:23] <lanodan> Ah got it in the display datasheet
