TMS570LS1114: TMS5701114CZWTQQ1, request for the programming specification

Hi Josel,

The Hercules devices contains an ICEPICK module to allow JTAG access to the scan chains. The JTAG port has the five standard IEEE 1149.1 interface pins (nTRST, TCK, TMS, TDI, and TDO) plus a return test clock pin (RTCK). TI JTAG-based emulators - XDS110, XDS100V2, XDS200, XDS560V2 emulators can be used.

The device can be programmed through CCS or Uniflash. 

Hi QJ,

Do we have a complete document/file for that?

Regards,

Josel

Hi Josel,

The JTAG follows IEEE1149.1 spec. The flash is programmed using F021 Flash Library which is also used by CCS and Uniflash. The F021 flash library is widely used by device bootloaders (UART, CAN, Ethernet, SPI, USB, etc).

Hi QJ,

Good day.

How can we download the bootloader using JTAG to the RAM? Does there exist a minimal IC connection for programming the Flash?

Regards,

Josel

Hi Josel,

You can use any IDEs that support Hercules devices for example TI CCS, Uniflash, IAR workbench, etc

Yes, the basic JTAG signals should be connected: nTRST, TCK, TMS, TDI, and TDO

Hi QJ,

Good day.

The customer knows how to connect signals to the JTAG interface. They support the programming of many chips via this interface.

For this device, we need to know clearly how to connect the device (supplies, clocks, etc.) to be able to program the Flash and how to download the bootloader to the RAM. Everything must be done by our (Elnec) hardware and software, the tools you mentioned in previous answers aren't options. Therefore I asked for the documents where is described how to download the bootloader to RAM.

Please advise.

Regards,

Josel
