JTAG Simulation by RM48 Hercules Development Kit (HDK)
Is there someone can help me?
1. Can I simulation my target board by JTAG interface of RM48 Hercules Development Kit (HDK) and CCS4? What is different operation with program opration?
2. If I have rm48 MCU and XILINX Spartan-3E FPGA, Can I share the Jtag interface?
I will recommend to update your CCS to version 5.2.1.00018
Here is the link:
This release has full support for RM48 emulation and flash download.
We do not recommend to daisy chain multiple device on the JTAG port but it should be possible.The FPGA device will have to be defined in the scan chain has "ByPass"

Thank you for your reply. I have been a basic problem that when I just want program a device by JTAG, I need supply the power to the device from my target or JTAG.
For my target board,Is JTAG power needle input or output?
If you are using one of our HDK board than yes the power supply has to be connected to the board.
If you are using the USB stick version, the USB port supplies the board and there is no need for external supply.When using the USB stick version, it is necessary to limit the frequency of the device to 100Mhz. At full speed, the current consumption is higher than what the USB port can deliver.
Thanks for your answer.I have other question.
I will build a application for industrial control with safertos, which MCU I should choose? rm48l950 or TMS570? I search them on line, there are few parts of the RM48 in stock. when I choose the rm48, is there any production risk? After the RM48, is there any MCU that I can choose ,which will be full compatibility with RM48L950 IN pin plant ?
The RM48 is a little endian device while TMS570 is big endian.
These 2 devices are in production and there is no risk at all to start designing with these products.The typical production lifetime is 10+years.
