1 Replies and 1871 Views Power Sequencing / Level Shifting / Ioff issues...  1871  1 Started by  Deleted User Hi, Can someone please confirm this for me: 1) I just spun a board with a SOM OMAP138, and I left the IO_VOLT_SEL pin floating, so that the IO signals are 3.3V. 2) I then have some ICs (RS485 transceivers, external SRAM) on my custom baseboard that are powered by a different 3.3V (which share the same digital ground as the SOM). The question is that even though both the SOM’s IO signals and the external circuitry’s IO signals are at 3.3V, do I still need the “dual rail” level shifters (sim...

1 Replies and 2286 Views How to use ADS901 on OMAP-L138 EVM  2286  1 Started by  Deleted User Hi, I am new to DSP world and started to work with OMAP-L138 EVM lately. I am using OMAP-L138 SOM. My application requires continuous sampling and post-processing of 1 MHz analog signal. I have gone through the uPP documents that is designed to interface cleanly with high-speed analog-to-digital converters (ADCs). OMAP-L138 EVM Kit came with User Interface Board which has ADS901 A/D converter attached with it. I want to use that A/D converter to sample analog signal using uPP and DMA features...

FSR1 is configured to be generated as external. CLKX1 is provided as the source for sample rate generator and CKR1 generated by sample rate generator. But, McBSP1 is not working at all, even though McBSP0 worked properly with the same configuration. The difference which i found out for McBSP0 and McBSP1 are in the layout of base boa...

2 Replies and 1937 Views slow connecting and running via XDS100  1937  2 Started by  keithhall I have recently started using an L138 EVM (SN 4711M0066) and find that it is very slow. When connecting to the on-board USB emulator for the DSP from CCS4 it takes 1 min 15s for the DSP wake complete mesage to appear. I am using the supplied GEL from the Win CE SD card and loading the test programs from the same. The console messages during the emulator connect sequence report core:300MHz, DDR:150Mhz so I assume that this is ok. printf() to the console seems to take about 1s per call. More impor...

Thank you in advance, David.

0 Replies and 1627 Views SATA not working on new layout  1627  0 Started by  rsmitch I am on the 2nd spin of ADC / DAC board using the SOM6748 and SATA is not working on the 2nd board. The SATA works on my first development board and I only made a few changes to the 2nd spin board to clean up some layout errors, but the SATA stopped working for some reason on the second layout. Question: What is the bare minimum that the SOM6748 needs for the SATA to work I cleared the pin mux to disable all other external functionality. So I'm basically just giving the SOM 5 volts (I think...

Are there any interfaces (pins, plugs) on the board on which I can connect / solder some cables to connect the SPI channel on the C6748 to the MPC5643L My MPC5643L already has an interface to do so all that is missing is the docking on the OMAP-L138 EVM board.
