I'm new to rtems and the leon in general. I've managed to build the samples provided by Gaisler and load (some) on my dev board: https://www.gaisler.com/anonftp/rcc/rcc-1.2/1.2.25/
The board is the GR-CPCI-GR740. However I'm trying to understand the network interface and can't seem to get it going. When I run the samples rtems-ttcp and rtems-ttcpw (for read/write respectively) the board configuration seems to fail. Checking the uart debug output shows the following: Activating Leon3 io port for smsc_lan91cxx (pio:FF902000 mctrl:FF903000) Failed to initialize grpci2 driver -2 Initializing network Can't bring smc1 up: No such device or address greth1: mii read[1] failed to 2.0 (0x9e004000,0x00001004) greth1: mii read[2] failed to 2.0 (0x9e004000,0x00001004) greth1: mii read[3] failed to 2.0 (0x9e004000,0x00001004) In rtems-ttcp.c I have tried swapping the #define statements: #define ENABLE_NETWORK #define ENABLE_NETWORK_SMC_LEON2 /* Define this is a SMC91C111 CHIP is available on the I/O bus */ /*#define ENABLE_NETWORK_SMC_LEON3*/ However I'm not entirely clear on the configuration. Would anyone have insight into this? Cheers, Diego
