What are the available integrated development environments for running VxWorks on PowerPC? Wind River's ICE is a bit expensive, costing more than $10,000. In addition to Wind River's ICE, what other c...
The wife of the tax bureau director, Lao Liu, went to the market to buy vegetables. She thought: If she said she was Lao Liu's wife, the price might be cheaper. So she walked to the vegetable stall an...
When enabling IO, TI enables all IO ports, such as the GPIOE port, which contains many IO ports. In reality, we may only use one pin in GPIOE and not the others. Isn't this a bit wasteful?Also, the mo...
After I added the RIP routing protocol component to the kernel, I tested it through two debugging boards. When I started it, riptask and riptimertask were both running, but there was no initial reques...
