Abstract
In early August, I was going to go to Youjing technology to get a chance to connect to the Youjing engineering site. If there is any de2 suspected zookeeper, I can ask you on behalf of me.

Introduction
I will go to Youjing in early August: the hardware design and practice of the machine's Virtual Machine [2008/8/3, 8/10, 8/17]. I have the chance to meet Youjing's engineering workshop, if you have any questions in de2, you are welcome to leave a message in this post. I can ask you for help.

Questions about zookeeper:
Q1. how can I restore the image captured by de2_lcm_ccd to the PC?
Q2. can I use a program to retrieve the clip captured by de2_ccd?
Q3. how can I collect data from the hardware design method to the SDRAM using C ++ on the NIO II?
I have solved this problem. How can I obtain the image obtained by CMOS ON THE niosii platform? (SOC) (DE2-70 builder) (nioii) (TRDB-D5M)

Q4. why cannot I use the proejct of control panel and Image Converter in de2_lcm_ccd?
The Youjing project said that at the beginning, image converter was built for the de2_ccd project, so it is not used for de2_ccd_detect and de2_lcm_ccd projects.

Q5.Why is the gpio and i2c_ccd_config of q7.de2 _ lcm_ccd working with wire transfer fail, and the exposure value cannot be set?
According to the answer from the root Youjing project, there is no such problem in the case of Tilde, which is caused by the issue of us II synthesis. How can I solve the problem that de2_lcm_ccd falls between the upper and lower sides and cannot set the exposure value? (SOC) (de2)

Q6. you cannot successfully upload the ZIP file system example created by yourself.

No CFI table found at address 0x00000000

How can I determine the response parameter of no CFI table found at address? (SOC) (nio ii) (de2)

Q7. how to use Modelsim-Altera to simulate de2 reference design?

When the information is

# ** Error: ../img_data.hex ( 1 ): Near " 0100000000 " : Syntax error , Unexpected " Integer Number " , Expecting " Identifier "
# C:/Altera/ 72 /Modelsim_ AE/win32aloem/vlog failed.

The Youjing Engineering expert said they didn't use Modelsim-Altera to simulate the niosii, so they didn't know how to solve this problem during the hour. How can I use Modelsim-Altera to simulate niosii? (SOC) (nio ii) (FPGA builder) (Modelsim) (de2)

Q8.DE2-70 flash how to set timing?
It has been resolved and will be further discussed on the blog.

Q9. how can I solve the Java program response generated in the nioii eds?

2008 - 8 - 5   8 : 47 : 09 -(Severe) generate: Java. Lang. illegalstateexception: Java. Lang. illegalstateexception: Java. Lang. numberformatexception: empty string
Make [ 1 ] :*** [ System_description/../obj/system. H-T ] Error 1  

Q.12 why does the read and write operations of sdram_control_4port have an offset?

Sdram_control_4port U6 (

......
// FIFO write side 1
. Wr1_addr ( 0 ),
. Wr1_max_addr ( 640 * 512 ),
. Wr1_length ( 9 ' H100 ),
......
// FIFO read side 1
. Rdw.addr ( 640 * 16 ),
. Rdw.max_addr ( 640 * 496 ),
. Rdw.length ( 9 ' H100 ),
.........);

According to the answer from the Youjing project, because the previous line is distorted when the Bayer pattern is RGB, it deliberately omitted the previous line, later, when we discuss the Bayer pattern to RGB, this section will be specially resolved.

Q.13 how to pull a video clip from the SD card?
Q.14 how can I use the de2_sd_card_audio example to play the next song at will?
According to the advice of the wojing project, please refer to the de2_70_sd_card_audio_player example of the DE2-70, and the example de2_sd_card_audio attached to de2 is the benchmark for the magnetic zone de-partitioning, that is to say, it is just a dead, and the example of DE2-70 is worse than just some, because the SD card is better than my research, I may not give a complete explanation in a short time.

Q.15 is it possible that de2's SDRAM will also run the receiver in the frame buffer at the same time?
According to the answer from the program, if we want to allow the 8 Mb SDRAM of de2 to run the runtime program for the frame buffer for the niosii, We have to compile the SDRAM Controller of the system on our own, this is a huge challenge for many people. If we really need a lot of SDRAM, for example, we need to use SDRAM as the frame buffer and run uClinux with it, it is recommended that the use of DE2-70, because there are two 32 mb sdram, a total of 64 MB, can be a large SDRAM as the frame buffer, another large SDRAM run uClinux, very abundant.

Recently, I have changed de2_ccd and de2_70_d5m_ltm to the Master/Slave architecture. If the architecture is successful, 8 MB of SDRAM can be used for the frame buffer at the same time for niosii. I look forward to it.

Q.16 I2C debug skills.
It has been resolved and will be further discussed on the blog.

Q.17 how does one control vga on the nioii?
According to the answer from the wojing project, currently, Altera does not provide such an IP address. We need to renew it ourselves.

Q.18 how can I store the data in a gray volume into the SDRAM?
How can we produce gray images in real time? (SOC) (de2) (TRDB-DC2)

Q.19how does niosii directly perform motion tracking by using the numbers of Apsara stack and flash?
Please refer to the following link for more information: How can I enable the system to operate on a single power? (SOC)
