On the surface, the man-machine program crashes and all functions cannot work properly.
This problem has appeared many times. It took a week to understand it. Later, we summarized the tracking process and analysis and provided three solutions.2 problem tracking 2.1 Tracking Step 1 -- top command viewing thread status

On JB, we sometimes find that the segv_accerr problem occurs when we run a good program on ICS and run it on JB. As mentioned in the previous article, modifying DSO in the hmi of the Hal module may cause a segment error.
When an error occurs, about the following information is output:
fault addr 3cde4bf43cde2000-3cde5000 r--p 00050000 b3:01 595 /system/lib/libwilhelm.so0x3cde4bf4
Here we can see that linker maps this segment of address into

To help mitigate the possibility of cyberattacks, ICS-CERT recommends that seven critical policies be built for industrial networks to improve their protection capabilities. The Agency claims that these seven major steps would allow FY to survive 2015 of the attacks reported in 98%.
Seven major artifacts protect industrial security
These seven key strategies are:
1. Build an application whitelist: only approved applications can be executed, so that the network can detect

tube control system strengthens the function of the PCS7 control system from improving the overall management of the workshop production, it tracks and participates in the production control of each link in the whole assembly line, makes the chemical reaction of raw material to the quality control of the semi-finished product and the packing and warehousing of the finished products to realize the whole integration automation. It also submits the relevant data information to the ERP system.2. Sy
the padding in the top and bottom directions, we first determine whether the height of the picture view is less than the height of the scrolling view, and if so, set the margin to be half the difference between the two, otherwise set to 0. Horizontal spacing We calculate in the same way. The padding for all directions is then set through the Contentinset property, which represents the distance uiscrollview the contents of the Uiscrollview itself.Run the program and you'll find that when you zoo
product supports dual Gigabit high performance Ethernet ports and provides a m.2 E-key socket for installing wifi/Bluetooth cards, plus 5 UART ports for rs-232/422/485 support, 12 GPIO interfaces, 1 can bus 2.0B interface, 4 USB 2.0 main interface, 1 SD card slots and one I²c 5V interface. RSB-4221 's high level of configuration fully confirms that this is not only an ideal hardware solution for the industrial market, but also has the flexibility to be able to handle more diverse application re
, may also require changes in the process, the most annoying of programmers is the frequent changes in demand, especially the program has been written more than half, but this situation is always unavoidable, and can not be fully blame to the customer or demand analyst. Using the code above, for example, the user might ask a similar request:First, you implement "addition" and "subtraction" in your program, and I want it to also calculate "multiplication" and "division".Second, your current
