i have 2 modules with W5300 chip in one rack, so they have equal power, reset timings and behavior.
Each W5300 chip is used in MACRAW mode.
I noticed no Link signal when they are directly connected after power on or system reset . This is a very often situation.
When connecting to switch or notebook Link is alway ok. Connecting them after other devices disconnection is also always ok.
I could solve this problem partly by applying a delay about 30 - 50 msec before hardware reset of w5300 chip on one of modules.
Each module must be equal with the same software.
How can i solve this problem?
