RTOS/AM3352: NIMU ioctl issue

Hi Paula:

I offer more detail information, i'm modifying this project:
NIMU_FtpExample_evmAM335x_armExampleproject


My code is here:
ret_code = NIMUIoctl (NIMU_GET_NUM_NIMU_OBJ, NULL, &num_device, sizeof(num_device));
if (ret_code <0)
UART_printf ("\n Rio Debug ==> NIMU_GET_NUM_NIMU_OBJ error code = %d \n", ret_code);
else
UART_printf ("\n Rio Debug ==> MAC NIMU_GET_NUM_NIMU_OBJ num_device = %d\n", num_device);

/* Allocate memory for the device table*/
dev_table = mmAlloc(num_device * sizeof(UINT16));


/* Get a list of all device index. */
ret_code = NIMUIoctl (NIMU_GET_ALL_INDEX, NULL, dev_table, num_device*sizeof(UINT16));
if (ret_code <0)
UART_printf ("\n Rio Debug ==> NIMU_GET_ALL_INDEX error code = %d \n", ret_code);

if_req.index = dev_table[0];

ret_code = NIMUIoctl (NIMU_GET_DEVICE_MAC, &if_req, &mac_address, sizeof(mac_address));

#endif
if (ret_code <0)
UART_printf ("\n Rio Debug ==> MAC Address error code = %d \n", ret_code);
else
UART_printf ("\n Rio Debug ==> MAC Address : 0x%x-0x%x-0x%x-0x%x-0x%x-0x%x\n\n\n",
mac_address[0], mac_address[1], mac_address[2],
mac_address[3], mac_address[4], mac_address[5]);
#endif

No matter what I call, it returns -22.

SetPhyMode:000021e1 Auto:1, FD10:64, HD10:32, FD100:256, HD100:128, FD1000:8192 LPBK:0

SYS/BIOS Ethernet/IP (CPSW) Sample application, EVM IP address: 192.168.1.4
SetPhyMode:000021e1 Auto:1, FD10:64, HD10:32, FD100:256, HD100:128, FD1000:8192 LPBK:0

Rio Debug ==> NIMU_GET_NUM_NIMU_OBJ error code = -22

Rio Debug ==> NIMU_GET_ALL_INDEX error code = -22

This is my cfg, I never change it.

The RTOS team have been notified. They will respond here.

Hi Rio, few questions, to see if I can reproduce in my side. Which board are you using? a TI board or a custom board? also could you please point me from where did you get NIMU ftp example?  Final, question, you mention your application is Ethernet/IP, is this your using your own stack running on CPSW? or are you using PRU-ICSS Ethernet/IP? I believe is the first option, but want to confirm.

thank you,

Paula
