How to issue "Software Reset" from UART HOST instead of pressing RESET button?

Dear Sir:

We found that SmartSnippets' "UART Booter" can upload firmware image to SysRAM and press RESET button of the HDK's motherboard to warm reset and run the firmware in the SysRAM.

Are there any ways that we can send "warm reset" command to chip and let it run automatically after we finish uploading firmware image?
I saw some texts about "new function (upload firmware image through JTAG) will be released in the middle of April, 2014". Can this new function support this function?

Hello Richard, The reset

Hello Richard, The reset button on our mother board generates a hardware reset signal, which is not possible to get triggered by software.
Software can only do a software reset.

Regarding the JTAG downloading, what you can do is,
1. download you software to system RAM through JTAG
2. JTAG script can modify the remapping address and issue a software rest command.
3. The chip will start running after software reset command is issued.

Can I also check you are working with the latest device version - should be 01 Silicon ? we just released that, and the new SDK went online yesterday to support -01 device. . We would need to swap your daugtherboard , main DVK motherboard remains the same.
Best Regards,

"Send Software Reset command through JTAG" is the only way that we can issue "Software Reset" from PC?

[Q2] There is ES4 chip in our daughter board.
Is the 01 Silicon same as ES4 or ES5 chip?

Hi Richard, ES4 chip is our

Hi Richard, ES4 chip is our pre-release device : i would recommend moving to a 01 daughterboard - this is supported with the new SDK we just launched.. I will contact you with a message to arrange a swap-out free of charge for you. Best Regard, JE_DIalog.
