Morning!
01:25
Morethink
I have reviwed most all of materials on github. Thanks a lot for friends of Apertus team. I think I can do something in embeded area. Anyone can send me the schedule of Apertus,especailly Schematic,PCB ,C programing and FPGA(EDK only)?
01:32
Bertl
sounds good, do you have access to a microzed?
01:35
Morethink
No, I used ZEDboard only.
01:37
Bertl
well, they are reasonably similar, but Beta will use the microzed as platform, so access to that would be definitely beneficial
01:37
Bertl
do you have experience in linux driver development?
01:39
Morethink
linux driver?
01:39
Bertl
device driver for the linux kernel
01:42
Morethink
I tested linux GPIO driver on ARM .I think I can do it.
01:43
Morethink
But I never make a really linux product driver
01:43
Bertl
well, do you like a challenge? :)
01:44
Bertl
we just finished the dual micro SD hardware and it requires kenel support to become really useable
01:44
Morethink
of course! I like challenge.
01:45
Bertl
basically it works already with the existing SD driver, so there is a good start, but it needs support for switching between the two cards
01:45
Bertl
and it would be really great to handle that transparently
01:49
Morethink
Let me start apterus from cards drivers
01:51
Morethink
Is there a specifaction or function description?
01:51
Bertl
a schematic of the latest version can be found here http://vserver.13thfloor.at/Stuff/AXIOM/BETA/microzed_sd/microzed_sd_v0.5_r1.1.pdf
01:52
Bertl
the external SD interface works basically identical to the internal SD, via the hardened zynq SD controller
01:53
Bertl
what we added on the external interface is an SD switch/level converter similar to the one already used on microzed/zedboard and some other devices on the I2C bus to do the switching
01:53
Bertl
(and a fan controller too)
01:54
Bertl
everything is interfaced via the PS PMOD port, on the zedboard that is port E
01:56
Bertl
for the specification: transparent switching would mean that the driver creates two fully functional mmc devices for userspace and interleaves the access to each card based on the requests
01:57
Bertl
i.e. if you access the first device, it ensures that the first card is selected before sending any commands and if the second device is accessed, it does the same for the second card
01:57
Bertl
the actual hardware access needs to use a semaphore machanism to prevent concurrent access, but otherwise it should be straigth forward
02:02
Morethink
Ok,I will make detail specification acordding to these infomation to confirm all of the fuctions.Then I will start make driver.
02:03
Morethink
Can you send me the pdf to my Email: Morethink@yeah.net? I can not access the web site.
02:04
Bertl
sure, no problem
02:06
Bertl
do not hesitate if anything is unclear
02:06
Bertl
*hesitate to ask
02:09
Morethink
OK
02:09
Morethink
thanks,Bertl
02:10
Bertl
you're welcome!
02:14
Morethink

excellent! do you have an idea what blocks your access to my site?
02:17
Morethink
Don't know yet. Maybe the company network forbidden some IP. I will try to access it in my home networks tonight.
02:18
Bertl
ah, okay, thanks!
02:18
Morethink
Welcome
02:22
Morethink
will Apertus use SD card as a video storge?
02:23
Bertl
not for video, the bandwidth would be too small, but for still images and similar
02:24
Bertl
the SD interfaces maxes out at 50MB/s which is by a magnitude small as what is required for proper raw recording
02:31
Morethink
still image is the first step of Apertus,isn't it?
02:32
Bertl
yes, that was the first step for alpha, and it will be the first step for beta
02:32
Morethink
OK
02:32
Bertl
but in general, some folks are more interested in high quality still images than in moving pictures :)
02:32
Morethink
I will try my best
