Sir, Is there any info on programming the MMB0 + ADS1282 boards without USB via the available data pins?

Is the MMB0 schematic available?

Thank You, Elio

You can connect to and program the MMB0 via the JTAG header (J8) located in the upper left of the MMB0. You will need to install a 100mil center header (or wires) to make the connection to a JTAG programmer.

The schematics for the MMB0 are located below. Use the one that corresponds to the revision of your MMB0 (the most recent should be Rev D)

Thanks Greg,

I have the revD version of the MMB0.

Now, I need the memory map of the JTAG registers that I can R/W , is this info available?

Regards from Elio.

Elio -

You will not program the ADS1282 registers directly unless you connect and use some sort of SPI emulator. Regarding the JTAG, typically you connect the JTAG emulator to the MMB0 to download/debug code that you have written to run on the DSP (and in doing so can manipulate the ADS1282 register via the C5507/9). For information on the JTAG and C5506/9, please review the documentation available @ www.ti.com for the TMS320VC5507/9A.

Thanks Greg,

I was hoping to avoid all the work of re-writing the code for the DSP - that has already been done by TI. If I know the JTAG registers, I only need to R/W just a couple

of registers to make everything work to my requirements. Thanks anyway.

Regards, Elio
