I would like to know if you are aware of a FreeRTOS+TCP port on the i.MX RT 1050.
In your opinion, can the ETH and PHY drivers that I find in the lwip examples in the SDK, provided by NXP, be used as they are for FreeRTOS+TCP or do they need to be adapted? And how hard could this adaptation be?

best regards

I do not know yet of a FreeRTOS+TCP port for “i.MX RT 1050”.

I did write a generic driver to configure Ethernet PHY’s. It recognises these ID’s :

/* ID's of supported PHY's : */
#define PHY_ID_LAN8742A		0x0007c130
#define PHY_ID_LAN8720		0x0007c0f0

#define PHY_ID_KSZ8041		0x000010A1
#define PHY_ID_KSZ8051		0x000010A1
#define PHY_ID_KSZ8081		0x000010A1

#define PHY_ID_KSZ8863		0x00221430
#define PHY_ID_KSZ8081MNXIA 0x00221560

#define PHY_ID_DP83848I		0x20005C90

You can find phyHandler.c here

That driver needs two functions:

typedef BaseType_t xPHY_Read( BaseType_t xAddress, BaseType_t xRegister, uint32_t *pulValue );
typedef BaseType_t xPHY_Write( BaseType_t xAddress, BaseType_t xRegister, uint32_t ulValue );

What you need to find out is how to program the transmission and reception of Ethernet packets on a “i.MX RT 1050”.

When you have specific questions about developing a +TCP Network driver, you can ask them here.
