I bought this model in full edition :

https://www.isee.biz/products/igep-processor-boards/igepv5-omap5432

It ships with a 4G micro-SD with an old, slow and boring Ubuntu on it.

I modified http://projects.goldelico.com/p/gta04-makesd/ from Nikolaus Schaller's website to build Debian/Pyra and Slackware images using the IGEPv5 hardware.

Have things yet to be fixed, e.g. I see only 1G RAM instead of 4G.

Odd there is a 1GB light version of that board is it possible you got that version instead?   Or maybe it has something to do with the device tree setup... not sure.

How does it even end up with 12.3 bogoMIPS? I wasn't aware the processor could even run that slow.

I have the Wi-Fi + the good reference on the board.

There's no boot parameters file, maybe the amount of usable RAM is fixed in the default.kernel.

No idea, I compiled a pandora kernel in 47mn with two cores instead of the 3:30 on the OP.

Wally I think may have the same 4GB version of that board, maybe you can get with him. the official Ti EVM we have the 4.0 Kernel, but I think Wally is stuck with an older 3.X version of the kernel.

Indeed, a very weird value :eek:

Are the bogoMIPS being calculated with the current cpu speed?

So could it be it clocks to 20MHz when idling?

bogoMIPS are calculated as part of the boot process. If it boots at just a few Mhz and the kernel sets the speed later then it would give very unusual results like this, I would think.

I don't know where to check/set the CPU frequency.

Looked around in /sys and /proc, but found nothing.

Here's the IGEPv5 latest kernel :

root@slackware:~# uname -r
3.8.13-0-omap5

well there is the cpufreq-info command...

also to note, running set @ 1.5Ghz, Kernel 4.0RC5:

Also to note about the bogoMIPS issue,

Is there a difference between bogoMIPS and bogomips?

differences between the /proc/cpuinfo

BogoMIPS    : 18.43 on the OMAP5

vs

bogomips    : 3191.64 on my x86_64 laptop.

is it just a decimal place difference?

edit: on searching for this information I found this quote: "BogoMIPS used to be the infamous, prestigious benchmark for Linux machines over a decade. Unfortunately - or fortunately - depending of point of view - the BogoMIPS number of the favorite machine BogoMIPS have little to nothing to do with actual processor performance."

so it may be a useless number.

I assume it's just a difference of output convention. My BeagleBoard says

BogoMIPS : 497.82

Check your Pandora. Mine is at home. :(

Hmm my 1Ghz @1100Mhz says..


BogoMIPS    : 1095.51


According to this metric we should stick with the DM3730  :)

Also, the instruction sets are different :

IGEPv5: swp half thumb fastmult vfp edsp thumbee neon vfpv3 tls vfpv4 idiva idivt

EVM : half thumb fastmult vfp edsp thumbee neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm

aTc compiled the kernel with some virtualization features enabled, looks like a few others too... the EVM seems to be missing swp, not sure how critical that is.
