I am wondering if there is a way (maybe a shield) using which I can connect two USB cameras to Arduino YUN
You could try a USB Hub.Although I doubt if there is enough bandwidth in the system to support two video streams, but I don't know for sure.
And AR9342:MIPS 74Kc@560MHz, 2.4GHz, 5GHz (dual band) v.s. AR9331 MIPS 24Kc@400MHz, 2.4GHzMIPS32 24 Kc delivers a performance of 1.6 DMIPS/MHz and 3.1 Coremarks/MHz. MIPS32 74 Kc delivers a performance of 1.93 DMIPS/MHz and 3.48 Coremarks/MHzAR9342:MIPS 74Kc@560MHz run 2 times faster than AR9331 MIPS 24Kc@400MHz.
I believe it failed because the Yun process (ARM/RISC) has a tendency to slow down when overloaded.
That is just a nonsense. The processor always works at the same speed irrespective of the amount of processing it has to do. In fact with it doing nothing or working out complex maths the processor knows no different.::::SNIP::::
Sorry pal, like most Linux users you know stuff all about hardware.
You could try a USB Hub....
FYI;-The heart of Yún is CPU - AR9331, here is the market position of it.AR9331 (MIPS 24k@400MHz, 1x1:1, 150Mbs/2.4GHz, PHY/100Mbs)AR9341 (MIPS 74Kc@500Mhz, 2x2:2, 300Mbs/2.4GHz, PHY/100Mbs)AR9344 (MIPS 74Kc@600MHz, 2x2:2, 300Mbs/2.4GHz, 450Mbs/5GHz, PHY/1Gbs)QCA9558 (MIPS 74Kc@720MHz, 3x3, 450Mbs/2.4GHz, 1300Mbs/5GHz, PHY/1Gbs)It is already on bottom of the food chain.
