- MX27 can support the largest LCD to 1024x768x16bit?
A: Yes
- BSP in the linux framebuffer driver LCD right?
A: Yes
- IDE interface support DMA transfer it? DMA's largest transmission system to achieve the number of speed?
A: support dma, IDE interface supports ATA-6 standards, Ultra DMA mode 0,1,2,3 and 4 with bus clock of 50MHz or higher.
Ultra DMA modes 5 with bus clock of 80MHz or higher.
- HOST of the biggest USB2.0 interface can support the transmission speed to reach the number?
A: HOST1 support Full speed, HOST2 support High speed.
OTG interface to support the High speed.
- Ethernet interface can support the maximum transmission speed can reach the number? Two Ethernet interfaces at the same time work? At this time the mouth of each net is the greatest number of speed?
A: You could work at the same time, DM9000 is 10/100M LAN, FEC can support full-deplex operation (200Mbps throughout) with a minimum system clock rate of 50MHz and half-duplex operation (100Mbps throughout) with a minimum system clock rate of 25MHz
- At the same time, the system can support the work of the video input interface 704x576x25fps, the two Ethernet interfaces 4mb / s, IDE hard drive 4mb / s, USB2.0 HOST 10mb / s it?
A: Apart from one network interface and the FEC can not use IDE hard disk, the other requirements to meet. If you want to use the FEC and the hard disk at the same time, you can use the PCMCIA interface of the hard disk, rather than CPU-ATA controller interface to connect the hard disk.
- System USB2.0 interface can support USB DVD burner right?
A: You could support an unknown driver.
- System can support USB2.0 interface DVD burner IDE hard drive to burn data?
A: You can support the USB DVD burner to support the unknown, not tested.
- System brought about by the H.264 encoder loop fitler support deinterlace it?nformation, detailed description of the problem.
A: H.264 is the MX27 chip codec hardware modules, its features can refer to the MX27 chip information.
- In the codec, the library function you provide?
A: Yes, the provision of library functions, and testing procedures.
- When our top multimedia applications directly call the function?
A: The library function and testing procedures are linux application layer code, the upper multi-media applications can be directly called.
- To provide for the number of function calls, whether or not the provisions of the manual chip codec standards realization can call, or part, if it is part of our ability to do so on the basis of the second development to achieve?
A: Yes, manual chip codec in the standard library functions are supported by secondary development can be done. Bsp together and we will help provide detailed documentation
- The whole of the development board includes the TFT LCD panel, or whether there are TV encoder support TV Output (PAL, NTSC)?
A: with TFT LCD, we offer two options, Sharp's 4-inch TFT LCD, resolution 480x272, Samsung's 3.5-inch TFT LCD, resolution 320x240 with TV encoder support, that is, tvout, chip model: Ch7013 LCD and tvout are external modules and the development board through the interface connected.
TVIN we can support the encoding of D1 30FPS, support encoding camera VGA 30FPS, D1 is still due to FREESCALE software update, the current can reach more than 20FPS.
- Can TVIN for the D1 30FPS long point of time? About 1 minute?
A: No, we are now a yuv file encoding, yuv file, each frame 0.5M, second is 15M, is a minute of 900M, we do not put so much yuv file SDRAM. The purpose of this test: evidence of the 27 pairs of D1 resolution yuv data h264 encoding, can achieve 27fps, which can be achieved proved mx27 spec design requirements: D1 encoding 30fps. Practical application is to yuv to tvin the D1 coding, rather than a yuv file encoding. But we have not yet fully tvin code to do a good job, so we encode yuv file to verify that 27 of the coding performance, in fact, tvin is work to be done by customers themselves, so that the current test should be sufficient. D1 coding can also be raised to 27.4, can also go to 28 or 29FPS.
Ifconfig eth0 192.168.0.180 But after the warning: BUG: warning at kernel / irq / manage.c: 118/enable_irq () 8 errors: 0 dropped: 0 overru this warning does not affect the normal use of the fec.
- Not to download their own kernel. linux startup menu and manual is also inconsistent, can not find "Update flash" this option?
A: Please note that there nandboot two miniboot and bootloader.
- I would like to achieve if the TV-IN input, by coding \ decoding, and then by the TV-OUT output, you can provide demo DEMO, or have good suggestions?
A: can be realized. With regard to the proposal, I do not know what effect you need..
- I wonder if you can test, if the input video signal is interlaced, I.MX27 whether by in-house hardware modules, rather than software, line by line signals the completion of the conversion?
A: I.MX27 can not be completed within the hardware module progressive signal conversion.
- Whether there is in the package and the source USB OTG drive, USB 1.1 or 2.0, whether the test procedure?
A: There are USB OTG driver source code and testing procedures, USB 2.0. Test methods and processes are introduced.
- Using the USB port, is it possible to download a new image using platform builder? I don’t see how this is possible as ActiveSync will not be running on the board?
A: At present, only through the network development board (DM9000) download a new NK. Have supported our own SD card to download the update.
- How would we use EBoot (or an equivalent)? Is it possible to debug using the USB port during the Boot Up process using platform? Again I don’t see how we can do this as ActiveSync will not be running.
A: The network KITL not work, so currently can not use PB to start debugging, only by looking at the serial information to debug.
- Are there any written directions/instructions on doing all this using USB/ActiveSync…
A: ActiveSync can refer to the use of ActiveSync software help files.
