Description:
cifX Toolkit Initialization function implementation. This file contains all functions
that need to be called by the application which wants to use the toolkit, to pass the
cards that need to be handled and initialize them all. This file also includes the
functions for downloading the firmware/configuration on startup and bring the card to live.
Changes:
Date Description
-----------------------------------------------------------------------------------
2023-04-27 Added cifXReadHardwareIdent() function, to read netX "ChipType"
2022-06-14 Added new user function to read IO buffer caching option
2021-08-31 - Reworked device type and chip typ detection in cifXStartDevice() / cifXHardwareReset()
- Adapted OS_Time() call to new parameter type definition
2021-08-13 - Fixed missing return of ulState packet errors in cifXReadFirmwareIdent()
- Removed "\r\n" from trace strings, now generally handled in USER_Trace()
2019-10-11 Propagate prototype changes of endianess conversion function
2019-03-01 Do not write PCIe configuration space during hardware reset of netX4000
based PCI hardware
2019-02-12 Skip update handling for flash based netX90/4000 devices
2018-12-10 Integrate detection function for netX90/4000 for ROMloader and while
firmware is running (the latter expects register block at end of DPM)
2018-10-10 - Updated header and definitions to new Hilscher defines
- Derived from cifX Toolkit V1.6.0.0
2018-09-24 Reworked startup structure, moved netx500 and netX51 hboot functions
to own source modules
