Hello! I have Toradex Colibri module ( PXA270 and PXA320 based - http://www.toradex.com/Products/Colibri_Modules ) and want connect them to Sagrad SG901-1028 module ( http://www.sagrad.com/index.php?option=com_content&view=article&id=55&Itemid=66 ) based on STLC450 chip. Now I add next code to plaform file (kernel 2.6.35.4): static mfp_cfg_t colibri_pxa320_ssp_pin_config[] __initdata = { GPIO83_SSP1_SCLK, GPIO85_SSP1_TXD, GPIO86_SSP1_RXD, GPIO84_GPIO, GPIO94_GPIO | MFP_LPM_EDGE_RISE, // IRQ GPIO95_GPIO, // SLEEP }; static struct pxa2xx_spi_master colibri_pxa320_spi_master = { .clock_enable = CKEN_SSP1, .num_chipselect = 1, .enable_dma = 0, }; static struct pxa2xx_spi_chip sagrad_spi_tuning = { .gpio_cs = 84, }; static struct spi_board_info colibri_pxa320_spi_chips[] = { { // Sagrad SG901-1028 or SG901-1039 - module p54spi, but... Joke from Nokia =) .modalias = "cx3110x", .max_speed_hz = 13000000, .mode = SPI_MODE_0, .bus_num = 1, .chip_select = 0, .controller_data = &sagrad_spi_tuning, }, }; static inline void colibri_pxa320_init_spi ( void ) { pxa3xx_mfp_config( ARRAY_AND_SIZE( colibri_pxa320_ssp_pin_config ) ); pxa2xx_set_spi_info(1,&colibri_pxa320_spi_master); spi_register_board_info( ARRAY_AND_SIZE( colibri_pxa320_spi_chips ) ); } and pach p54spi.c for proper SPI speed (XScale have maximum SPI rate 13Mhz) with addition module parameter: static long p54spi_max_rate = 24000000; module_param(p54spi_max_rate, long, 0444); MODULE_PARM_DESC(p54spi_max_rate, "maximum spi bus frequency"); and replace string with spi->max_speed_hz = 24000000; to spi->max_speed_hz = p54spi_max_rate; Also i got firmware 2.13.0.0.a.13.14.arm from linux-wireles. After loading module with proper command line, I see message cx3110x spi1.0: firmware boot failed and no other error/warning message presents. SPI signals like good. phy0: p54 detected a LM20 firmware p54: rx_mtu reduced from 3240 to 2376 phy0: FW rev 2.13.0.0.a.13.14 - Softmac protocol 5.6 phy0: cryptographic accelerator WEP:YES, TKIP:YES, CCMP:YES cx3110x spi1.0: loading user eeprom... phy0: hwaddr 00:02:ee:c0:ff:ee, MAC:isl3820 RF:Longbc x3110x spi1.0: firmware boot failed What's trouble? Incorrect firmware? Unsupported (so slow) SPI rate? I try load another firmware from 2.13... series - result: firmware boot failed. I also try load firmware cutted from Sagrad source (version 2.19....) result is same: firmware boot failed. What is my next step for this idea? -- Sincerely, Alex A.
