The workaround for this until the new tools release is,
1. Use the xscope_core_bytes() function, this does not have the issue
or
2. Use the xscope_bytes() function but always pad your data to at least 8 bytes.

Re: xcore-200 JTAG
So the 2 TAP's have now been combined into 1 at the top level in the device, this makes things quite a bit simpler. There is a new instruction in the top level TAP for booting from JTAG and setting the PLL. SET_TEST_MODE 0x8 - Load chip test mode register with DR · The chip test mode control registe...

Re: xcore-200 JTAG
Apologies, the JTAG section still requires updates as there have been some changes. As far as I know yours are the only other tools that require this information. The changes that you will need are, - The JTAG ID is 0x5633 - There is only one top level tap (rather than the 2 in XS1) - The same instr...

Yes QSPI boot, the embedded flash parts have QSPI flash internally.Folknology wrote:Thanks Xmatt
Does the boot actually use QSPI to improve performance as well as overlays?

Re: New XMOS chips??!
- The links are fully compatible with the XS1-L/U/A series of devices.
- MSEL is not needed on xCORE-200, JTAG boot mode is selected via an internal register in the top level JTAG TAP.

XTAG issues on Windows 7 (64 bit) and USB 3 ports
All versions of the XTAG (XTAG-2 / XTAG-3 / XTAG-Pro / startKIT) have issues enumerating on 64 bit windows 7 when used with USB 3 ports.
Is there anything that can be done to make them work correctly?

There is an library for implementing the communication with xscope host applications here if you want to see how to parse the data from the socket interface from xrun.

Re: JTAG write to Node Config registers?
The node configuration registers are read only via JTAG.
The only registers that can be written directly via JTAG are those used for interaction with the debug ROM and to put the device into debug by generating a debug interrupt.
