Sep 24 16:11:13 <zergos> hello
Sep 24 16:11:31 <zergos> i have a problem with GCC i got this error : region sram is full
Sep 24 16:12:01 <zergos> i not understand how to avoid
Sep 24 17:44:20 <Weaselweb> zergos: 1st, this has nothing to do with jtag. 2nd, i guess your code size for this sram section is too big
Sep 24 18:08:54 <zergos> Weaselweb, thx for answer, i know is big, but how this happend interest me, and about jtag i have a problem, with 1 of my boards, have you already used board with AT91sam9261 ?
Sep 24 18:14:38 <Weaselweb> zergos: no, not 9261. but 9260, 9263 and 9g20
Sep 24 18:15:08 <Weaselweb> afaik all have different sram sizes and/or blokcks
Sep 24 18:15:42 <zergos> Weaselweb, yes, with at91sam9 i still not arrive to connect on jtag
Sep 24 18:16:08 <zergos> looks something not good in config script
Sep 24 18:16:20 <Weaselweb> be sure, you run jtag_clock 1/6 of core clock at maximum
Sep 24 18:16:39 <Weaselweb> especially when running in slow clock mode
Sep 24 18:17:06 <Weaselweb> paste error messages, otherwise nobody may help you
Sep 24 18:17:46 <zergos> Error: Could not probe bank: no QRY
Sep 24 18:17:47 <zergos> Try workaround w/0x555 instead of 0x55 to get QRY.
Sep 24 18:17:47 <zergos> Error: Could not probe bank: no QRY
Sep 24 18:18:06 <Weaselweb> this is from probing NOR flash
Sep 24 18:18:10 <Weaselweb> using CFI
Sep 24 18:18:40 <Weaselweb> if you don't have one, remove the flash bank entries from your config file
Sep 24 18:19:58 <zergos> flash bank at91sam9261.flash cfi 0x40000000 0x1000000 2 2 0 $_TARGETNAME
Sep 24 18:20:53 <zergos> but flash is NAND not NOR
Sep 24 18:21:00 <Weaselweb> that sound like a 16MiB 16bit NOR-FLash on chip select 3 iirc, do you have such device mounted?
Sep 24 18:21:18 <Weaselweb> afaik nand is properly supported from openjtag
Sep 24 18:21:22 <Weaselweb> isn't!
Sep 24 18:21:31 <Weaselweb> just remove this line
Sep 24 18:22:32 <zergos> but how interface will know about flash chip
Sep 24 18:23:00 <zergos> i m sorry, its first time i use board with external flash and ram
Sep 24 18:23:12 <Weaselweb> afaik, you can't program NAND flashes from openocd, use sam-ba for that
Sep 24 18:23:46 <Weaselweb> or u-boot
Sep 24 18:23:55 <zergos> ah
Sep 24 18:24:03 <Weaselweb> which needs to be flashed first, though :)
Sep 24 18:24:13 <zergos> uff
Sep 24 18:24:14 <zergos> :D
Sep 24 18:24:15 <zergos> i see
Sep 24 18:24:31 <zergos> so jtag is not userfull in this case ?
Sep 24 18:24:37 <Weaselweb> did you read sam4linux.org?
Sep 24 18:24:47 <zergos> not
Sep 24 18:25:11 <Weaselweb> well, it could be usefull i you have a nand programm application which you can write to sram or sdram and run it from there
Sep 24 18:25:24 <Weaselweb> but otherwise, I would use sam-ba to program NAND flash
Sep 24 18:25:58 <zergos> and in case is NOR ?
Sep 24 18:26:05 <zergos> is possible over jtag ?
Sep 24 18:26:19 <Weaselweb> yep, i programmed NOR several times using openocd
Sep 24 18:26:28 <Weaselweb> this is plain CFI, hopefully
Sep 24 18:26:33 <zergos> i see
Sep 24 18:26:43 <zergos> so i made mistake by buying my board :(
Sep 24 18:26:46 <Weaselweb> some devices seem to be buffy
Sep 24 18:27:18 <zergos> now have to understand why is presend JTAG port on board
Sep 24 18:27:31 <zergos> if cant program over there
Sep 24 18:27:32 <Weaselweb> well, your dealer should have some descriptions how to start
Sep 24 18:27:45 <zergos> yes u-boot 
Sep 24 18:27:56 <zergos> but in this case why is there jtag
Sep 24 18:28:02 <Weaselweb> some other debuggers can program nand, openocd seem to support this not well enough
Sep 24 18:28:15 <zergos> aha
Sep 24 18:28:16 <zergos> i see
Sep 24 18:28:49 <Weaselweb> is IS possible to flash NAND using jtag, but openocd can not AFAIK
Sep 24 18:28:56 <Weaselweb> to make this clear :)
Sep 24 18:28:59 <zergos> and about your boards, does their chipset got embedded flash memory ?
Sep 24 18:29:26 <Weaselweb> nope, either NAND or NOR
Sep 24 18:29:37 <Weaselweb> which means external flash memory
Sep 24 18:29:50 <zergos> ok
Sep 24 18:30:03 <zergos> have did any application with encrypted flash ?
Sep 24 18:30:04 <Weaselweb> iirc 9g45 or 9g10 have internal flash memory
Sep 24 18:30:20 <zergos> + external ,
Sep 24 18:30:21 <zergos> ?N
Sep 24 18:30:30 <Weaselweb> encrypted? had nothing to do with that yet
Sep 24 18:30:52 <zergos> i mean against dump :D
Sep 24 18:31:40 <Weaselweb> preventing erasing? depends on the device, some have block write protection
Sep 24 18:31:43 <zergos> about openocd, what for is Nand function ?
Sep 24 18:32:13 <zergos> i seen this in 0.1
Sep 24 18:32:15 <zergos> oups
Sep 24 18:32:17 <zergos> 0.4.0
Sep 24 18:32:28 <Weaselweb> I read once about NAND in some openocd comment this is not finished yet. but coult be outdated. didn't tried yet again
Sep 24 18:32:34 <Weaselweb> that was < 0.4.0
Sep 24 18:33:03 <Weaselweb> sry, but I'm afk now
Sep 24 18:33:13 <zergos> oki thank you for all answers
Sep 24 18:33:22 <Weaselweb> you're welcome
