Part Number: TMS320F28377S Hi, One of my customer use our F28377S with LAN9252, and connect GPIO34 directly with CS. But here is 1 platform(out of 30 platforms) has communication issue. the data transmission is wrong. after customer disconnected CS between these two ICs and pull up LAN9252's CS pin, the issue is solved. what's the reason? is it due to the driving ability of GPIO34? what should customer do to fix it?
