Industrial IO Revision Information¶
Background¶
The Industrial I/O board was initially developed for a specific application in the early lifespan of the MityDSP-L138F module. As demand for an off the shelf evaluation host board for the MityDSP-L138F module increased, Critical Link released the Industrial I/O host board as the evaluation host board in the developer's kit.
The Industrial I/O host board has gone through a few minor revisions and a few early adopters of the MityDSP-L138F module may have different board revisions on hand. This page is intended to outline the revision history of the board as well as provide information as to which Xilinx Constraints file in the development kit applies to which board.
To determine which board revision you have, please see the photo below and locate the Part Number on the sticker on the lower left top side of the PCB.
The table below is chronological and contains the mapping of the board number to the UCF file for FPGA based modules as well as the schematic and a brief description of the change from the previous revision. The UCF files are located in the examples/industrial_io/fpga/vhdl folder of the most recent board support package. In general, customers receiving development kits after March of 2011 should use the IndustrialIO_rev_C.ucf constraints file.
NOTE You must have a valid registered account and be logged-in in order to download the schematics.
Altium Design Files: Customers who have purchased the development kit and are designing a custom base board to use the MityDSP-L138 can request the Altium Design Files from Critical Link by e-mailing info@criticallink.com
| Part Number (PCB label) | Relevant UCF File | Description of Change | Schematic | Datasheet | PCN | |
| 80-000268RI-1 A | IndustrialIO_rev_A_B.ucf | Initial Revision of board | N/A | |||
| 80-000268RI-1 B | IndustrialIO_rev_A_B.ucf | Add push button for EXTBOOT to support UART programming of dead board. Force RS-485 Receive always on. | N/A | |||
| 80-000268RI-1 C | IndustrialIO_rev_C.ucf | Edge connector assignments shuffled to support use of FPGA-less modules with DVI interface | N/A | |||
| 80-000268RI-1 D | IndustrialIO_rev_C.ucf | Silkscreen designators moved for better readability, solder mask tailored for improved manufacturing yield | ||||
| 80-000268RI-1 E | IndustrialIO_rev_C.ucf | Switchable +5 volt power added to USB0 port to support host/OTG mode (U101). Connect Audio SYSCLK to AHCLKR OMAP signal. Connect SPI1 to DSD1791 CODEC control port to allow control of gain, etc. | N/A | |||
| 80-000268RI-2 A | IndustrialIO_rev_C.ucf | RS485 driver removed from Profibus connector and raw OMAP-L138 UART lines connected, supports using adapter card for either RS-232 or RS-485 protocols. Resolve parts obsolescence (passives). All 80-000268RI-2 A boards were reworked to include reset circuit added in 80-000268RI-2 B. | N/A | |||
| 80-000268RI-2 B | IndustrialIO_rev_C.ucf | Reset circuit added to force DVI control chip to reset on power up. Correct pin issue on J100 (USB OTG port), connect pin 4 to USB ID and pin 5 to ground. | N/A | |||
| 80-000268RI-2 C | IndustrialIO_rev_C.ucf | Updated +5V isolated power supply circuit and USB Host Connector for availability issues. +5V isolated supply current reduced to 100 mA. | PCN 20121203000 | |||
| 80-000268RI-3 A | IndustrialIO_rev_C.ucf | Pull down resistor (R110) on USB ID0 can cause failure in peripheral mode, no longer populate it and update parts for obsolescence. | N/A | |||
| 80-000268RI-3 B | IndustrialIO_rev_C.ucf | Updated for DFM issues to fix DVI fallout. Changed system reset circuit to open collector. | ||||
| 80-000268RI-3 C | IndustrialIO_rev_C.ucf | Updated assembly note. | ||||
| 80-000268RH-3 C | IndustrialIO_rev_C.ucf | Renamed to 'RH' and listed non-industrial parts | N/A |
Note in the MDK, under examples/industrial_io/ there are project folders for building an FPGA module supporting DVI or LCD. These projects have the name format: build_lcd_rev_XX or build_dvi_rev_XX. In this cases, the rev_XX should map to the rev_XX of the UCF files above. E.G., boards that require IndustrialIO_rev_C.ucf would use project build_lcd_rev_c for the example project supporting the LCD interface.
