| 17:56.07 | RaYmAn | low-speed serial seems to be vaguely standard across a lot of SoC's though :) |

| 22:09.31 | furan | thanks guys |
| 22:09.40 | furan | hno: yeah it's a mess |
| 22:34.05 | Marex | hno: heya! :) |
| 22:34.25 | Marex | hno: did you get time to check the upstream goo ? |
| 22:35.55 | hno | Marex, still fighting with DRAM setup on A13. in general. |
| 22:36.18 | Marex | hno: all righty, good luck then :) |
| 22:36.41 | hno | I hope to see some life from SPL in a minute. |
| 22:37.05 | hno | But no... |
| 22:38.16 | Marex | hno: SPL doesn't start for you at all ? |
| 22:39.04 | Marex | hno: if you have serial port, you can call "serial_init()" and "serial_puts()" to pump out some debugging symbols basically right after you have stack set up (after you leave start.S and execute C code) |
| 22:39.05 | hno | The DRAM controller never finishes it's initialization for some reason. |
| 22:39.17 | Marex | just remember you need CONFIG_SPL_SERIAL_SUPPORT in your include/configs/...h |
| 22:39.23 | Marex | hno: oh this |
| 22:39.43 | hno | Running it under gdb via JTAG |
| 22:40.46 | Marex | hno: might be a timing issue due to the single stepping ? |
| 22:40.51 | Marex | or maybe you break it somewhere ? |
| 22:41.17 | Marex | hno: I think I won't be much help really, I have only a very blurry idea about this particular chip |
| 22:41.26 | hno | Does not seem to be a timing issue. Hangs at same location without any breakpoints. |
| 22:41.40 | furan | hno what are you fighting? if the source is out, I guess I'm not sure what you're doing - are you writing new drivers for these things? |
| 22:41.49 | furan | it sounds cool though |
| 22:42.04 | hno | furan, source is not out for initial boot process on A13. |
| 22:42.41 | Marex | hno: why does it hang ? the core halts ? |
| 22:42.58 | Marex | hno: aren't you hitting some exception, like DABT due to accessing uninited memory ? |
| 22:43.13 | hno | It's a loop waiting for the dram controller to flip a bit saying it's ready. |
| 22:43.30 | hno | no memory accesses yet. |
| 22:43.54 | Marex | oh, then you're likely missing some configuration ... it's hard to tell without ref. sources or datasheet |
| 22:44.09 | Marex | you can maybe setup HW watchpoints and trace the original code that does the init though ? |
| 22:45.37 | furan | oic |
| 22:45.47 | Marex | furan: wat ? :) |
| 22:45.52 | furan | oh i see |
| 22:45.56 | furan | responding to hno :) |
| 22:46.17 | Marex | hydrogen nitrogen oxygen :p |
| 22:46.26 | furan | I have yet to use jtag to debug, not even sure what sw to use, even though I have dongles for it for fpga stuff |
| 22:46.35 | hno | HW watchpoints during original initialization process would be interesting. Need to try that. But currently matching register dumps to make sure I set up the registers right. |
| 22:47.03 | furan | is there a tutorial somewhere on doing jtag debuggiing? |
| 22:47.05 | Marex | hno: you usually need to write the registers in correct sequence |
| 22:47.08 | furan | debugging |
| 22:47.15 | Marex | furan: read up on OpenOCD ... that's cool |
| 22:47.24 | furan | ok |
| 22:47.33 | Marex | furan: for stuff like programming xscale chips, read up on openwince-jtag (now urjtag) |
| 22:47.56 | Marex | furan: when you want to go to next level, get abatron bdi3000 :p |
| 22:48.12 | Marex | furan: and then the only way up is probably the lauterbach one ;-D |
| 22:48.24 | Marex | puts off the drool |
| 22:48.54 | furan | haha ok |
| 22:49.26 | Marex | hno: another interesting thing you might want to try is qemulating the init code (in qemu) ... you can trap hardware accesses there really easily |
| 22:49.31 | furan | is there anything else usually on the jtag chain besides the cpu? |
| 22:49.38 | furan | on allwinner devices |
| 22:50.13 | Marex | furan: no idea about allwiener ... but there might be |
| 22:51.56 | hno | furan, no idea what's on the chain. Only know how to access the cpu. |
| 22:56.56 | Marex | hno: the JTAG is a bus, like any other ... and there can be multiple devices connected on it |
| 22:57.19 | Marex | hno: usually, there's only the CPU, alone, sad ... but there might be eg. an FPGA on the same JTAG bus |
| 22:57.50 | furan | well I was wondering if flash was on jtag but the jtag pads I've seen are right next to the cpu |
| 22:58.05 | furan | so perhaps not |
| 22:58.30 | penguin42 | don't you normally have to do evil things like wiggle the CPU pins over JTAG to do flash writes? |
| 22:58.32 | Marex | furan: that's not very likely |
| 22:58.38 | Marex | penguin42: yes |
| 22:58.40 | hno | There is no JTAG chaining to external components. But there is multiple CPUs within the chip. |
| 22:59.02 | furan | penguin42: no |
| 22:59.19 | Marex | hno: the multiple CPUs business in case of the armv7 is handled by that coresight goo arm has |
| 22:59.26 | furan | usually they're just on the jtag chain as independent devices (flash) |
| 22:59.43 | furan | I have a lot of fpga boards that are like that, fpga and flash in the same chain |
| 23:01.54 | hno | furan, I don't see any JTAG signals in the normal NAND pinout. |
| 23:02.42 | Marex | furan: I didn't see too many flash chips with JTAG pads ;-) |
