Part Number:OMAP-L138
Hi,
I am currently using OMAP-L138 processor. I have been working with C6748 processor in which I have implemented a DMA chaining which was initiated by a synchronous signal at 256 kHz.
1.The synchronous input chained a DMA event to a transfer 2. (TCCHEN enabled) .
2. Moves a character from an array to a single variable, and is chained to SPI event. (ITCHEN and TCCHEN enabled).
3. The SPI event then transmits the 8 bit data and is chained to transfer 2. ( ITCHEN enabled ) .
The process was working well in C6748 processor in which a 40 bit data is transmitted after the each synchronous event.
When I migrated to OMAP with the same project, The 40bits SPI transfer is not happening in alternate synchronous cycles.
What could be the issue ?
i) Non OS environment using Code Composer Studio and JTAG interface.
ii) ARM part is not programmed.
Thank you in advance for any help you can provide.
