The driver code checks for it, and will return a valid answer if its a bcm2709, bcm2835, bcm2836, or a bcm2837. Code is:
Code: #define CPUINFO_BUFSIZE (16*1024) // Should be large enough for now
static platform_t check_platform(void)
{
FILE *fp;
char *buf;
size_t fsize;
platform_t rv = RPI_UNSUPPORTED;
if(!(buf = rtapi_kmalloc(CPUINFO_BUFSIZE, RTAPI_GFP_KERNEL))) {
rtapi_print_msg(RPSPI_ERR, "hm2_rpspi: No dynamic memory\n");
return RPI_UNSUPPORTED;
}
if(!(fp = fopen("/proc/cpuinfo", "r"))) {
rtapi_print_msg(RPSPI_ERR, "hm2_rpspi: Failed to open /proc/cpuinfo\n");
goto check_exit;
}
fsize = fread(buf, 1, CPUINFO_BUFSIZE - 1, fp);
fclose(fp);
// we have truncated cpuinfo return unsupported
if(!fsize || fsize == CPUINFO_BUFSIZE - 1) {
rtapi_print_msg(RPSPI_ERR, "hm2_rpspi: Platform detection memory buffer too small\n");
goto check_exit;
}
/* NUL terminate the buffer */
buf[fsize] = '\0';
if(strstr(buf, "BCM2708")) {
rv = RPI_1;
} else if(strstr(buf, "BCM2709")) {
rv = RPI_2; //for RPI 3 too
} else if(strstr(buf, "BCM2835")) { // starting with 4.8 kernels revision tag has board details
char *rev_val = strstr(buf, "Revision");
if(rev_val) {
char *rev_start = strstr(rev_val, ": ");
unsigned long rev = strtol(rev_start + 2, NULL, 16);
if(rev <= 0xffff)
rv = RPI_1; // pre pi2 revision scheme
else {
switch((rev & 0xf000) >> 12) {
case 0: //bcm2835
rv = RPI_1;
break;
case 1: //bcm2836
case 2: //bcm2837
rv = RPI_2; // peripheral base is same on pi2/3
break;
default:
break;
}
}
}
}
check_exit:
rtapi_kfree(buf);
return rv;
}
And all the c style indenting has been stripped, so how do I post code? This sucks.
Thanks everybody.
Cheers, Gene83

greetings,
I have manged to build u-boot as per http://opensource.rock-chips.com/wiki_U-Boot . However, after burning the images to SD card, booting stops before starting my built version of u-boot, i.e., no u-boot prompt!
Serial console output below, also, further down build details.
Can anyone please shed light whats wrong in the process ?
thanks

Had a working Android 7.1.2 eMMC. Not sure what I did to it but now it boots to the Recovery Menu but there's no keyboard or mouse response. Can't move to any selection in the menu. Reload the eMMC? Boot to an SD Card linux image and fix it from there somehow? Thanks for any tips.

| Mpeg2 playback broken in Android 0.3.6 firmware in Kodi |

1080p Mpeg 2 video playback is broken in latest Android firmware 0.3.6
It now plays with ffmpeg CPU instead of AMCodec(Mediacodec) hardware accelerated in Kodi 17/18 and use 100% CPU.
Eg. 720x480 DVD resolution videos look much smoother now using ffmpeg to play but 720p/1080p plays with skipped frames since it is not hardware accelerated.
Can it be changed so under 720x480(DVD) resolution mpeg 2 videos play with ffmpeg but the rest play with Mediacodec hardware accelerated?

| pcsx rearmed on rock64 debian stretch does not go fullscreen |

Hello,
anyone else tried pcsx rearmed on ayfan's debian stretch image?
My experience so far is:
If I compile it on rock64 I get wether neon nor dynacrec support which leads to a working build that is way to slow.
Another approach was to build pcsx reamerd on a raspberry pi 3 and copy over the resulting build. Don't build with neon on raspy, too but at least with the very needed dynarec support. Copied the resulting build over to the rock64: Works and is fast enough thanx to dynarec. (Mulltiarch must be installed, to make it work this way).
One Problem remains:
I only get SDL-Window-Output. No fullscreen. Any ideas?
BTW: Controller works too, tried a Steamcontroller with sc-controller.

Just wondering how you guys mount your board? I tried to use some of the screws left over from PC motherboards. They were often supplied with a million screws for this or that. Anyway my smallest screws would not fit the tiny ROCK64. Even the small brass nuts for offsetting a motherboard from its surrounding case would not fit. Dare I say it but - can we enlarge the hole a tiny bit? Or is this a big no-no. Looking for ideas on this.

my first impressions |

I have had the laptop for over a month or so and my first impressions are: excellent for a ~$100 laptop! My 12 year old son claimed it as his and wanted to use it for his laptop next year at school. I had to pry it from his hands!
There are a few things that bother me, though, and a few software issues are well.
Hardware:
The display/lid section is heavier than the keyboard section and is a bit difficult to open as the hinge needs to be stiff and lifts up with keyboard, so it takes two hands to open. I like the keyboard and actually feels nice, although the space bar seems flimsier than the rest of the keys.
Standby/suspend battery life is quite excellent. I had forgotten about it, and turned it on after a week or two, and still plenty of battery left.
It seems hardier than I had expected it to be.
Software:
Android - I didn't spend too much time with android here, other than to see that it ran and I could do a few things with it.
Linux - My biggest niggle is that I could not get bluetooth audio working. As in a bluetooth speaker. It would always just play through the speakers, which indicates a (hw)routing issue, which a way too quiet. Ok for a quiet room.
Some flickering of the display from time to time, but generally is ok.
I installed LXQT and am happy for the performance, noting that this is not a beefy developers laptop.
