XJtag can not find L1 in my board!
Hi Hacker: My new design board use one L1. I checked the boards, no abnormal conditions according to the Hardware design checklist.http://www.xmos.com/products/silicon/xs1-l1 But I still cannot see L1 using XDE 11.2 in debug configuration. I dont think this is the solder problem. I think this is a p...

Re: XLink (-L) Non-volatile Memory and I/O Service Board
If there is a Xlink2Local (like PCI bus / local bus) service, that's great.
or if there is a Xlink2APB (arm bus), cool!

Re: How to use the same memory in multi threads?
Hi Segher: Indeed the sharing buffers is a hot point. Use channel to pass the big buffers to other threads is not as good as to pass the reference. Think about a scenario, one thread has one large size data and other threads want to read this large size data to process. But how to pass the reference...

Re: How to use the same memory in multi threads?
Hi Hacker: I think over the access of the same memory between threads in a core. How to implement? Through channel tell the threads where the shared memory location? Or directly assign the memory address but how? Can you give an example? By the way if the access of the same memory between 2 threads ...

hi Hacker:
Sorry, I check my flash type again, it's at25df021.
I think xmos support it.

fl_connect() fail problem?
hi hackers: The system can be boot from spi flash. I want to upgrade images in the flash, so I follow the tool guide demo code. But I found fl_connect() always fails, always return nonzero. I check the bus using logic-analyzer. The XMOS first send hex code AB to wakeup SPI flash. Then send 9F comman...

How to write Interrupt/Exception Handler?
hi: Do somebody write interrupt/exception handler? Or Is the interrupt/exception not available for users? By the way, I see UART code in http://github.xcore.com/sc_uart/generic.html In the uart_rx_impl.xc, there is a function static inline void trap() { asm("ecallf %0" : : "r"(0)...

How to use the same memory in multi threads?
hi all: In a core, how to use the same memory location in the multiple threads in a core? Have any one done the ways? I hope the memory pool is used for data & control processing. How to set the compiler to ignore these pool memory range? Or there has the lib to manipulate these memory pool? Tha...
