Ethernet ONLY on PIC32MZW1

Hello, I'm starting on PIC32MZW1 (Harmony V3) curiosity board and would like an example that ONLY uses Ethernet (no wireless).1-Is there an example with just the Ethernet interface but suitable to my board? Since I don't have any other option or input, I'm working on the dual interface example: wire..

Fails to write to KSZ9897 registers with regs_bin application

Hi, I'm working with the KSZ9897 switch on my board. The KSZ9897 switch is connected to the CPU via SPI0.0.My program runs above linux-4.19.152 with the latest KSZ9897 driver. In the kernel (using the KSZ9897 driver), all read/write operations works fine !But I also need to make some read/write oper..

EVB-KSZ9477 DSA Does not work with Latest linux kernel

Hi, I am trying to test the DSA switch using EVB-KSZ9477 with latest kernel. The problem occurs in ksz9477_reset_switch() when reset switch command is sent. The value of 0x6301 register is set to 0x08 before that command and changes to 0x10 after executing the command. Has someone observed this issu..

KSZ8081RND: Linux works, Bootloader cannot write registers

Hello! I am currently facing a strange problem with an KSZ8081RND connected to an i.MX6Solo on a custom 3rd party board (i.e. no schematic, sorry). While the PHY works perfectly on Linux (linux-imx 4.14.98) I have yet been unable to get it to work in the Bootloader (U-Boot/Barebox): it is possible ..

PIC24 + ENC28J60 Ethernet – How to start?

Hello! It needs to be said that I'm a newbie in this type of field (MCUs, that is), so please forgive the vagueness of my questions. Now let me cut to the point: 1. I'm trying to build a web-controlled ticker / creeping line in Proteus VSM. 2. For this purpose I chose PIC24F128GA010 + ENC28J60 (..
