From eb9401e3ebfa6a1550522be28895af461137f797 Mon Sep 17 00:00:00 2001 From: wdenk Date: Mon, 11 Nov 2002 02:11:37 +0000 Subject: * Patch by Andreas Oberritter, 09 Nov 2002: Change behaviour of NetLoop(): return -1 for errors, filesize otherwise; return code 0 is valid an means no file loaded - in this case the environment still gets updated! * Patches by Jon Diekema, 9 Nov 2002: - improve ADC/DAC clocking on the SACSng board to align the failing edges of LRCLK and SCLK - sbc8260 configuration tweaks - add status LED support for 82xx systems - wire sspi/sspo commands into command handler; improved error handlering - add timestamp support and alternate memory test to the SACSng configuration --- board/sacsng/sacsng.c | 21 +++++++++++++++++++-- 1 file changed, 19 insertions(+), 2 deletions(-) (limited to 'board/sacsng/sacsng.c') diff --git a/board/sacsng/sacsng.c b/board/sacsng/sacsng.c index 0f0f0e6..19dbb97 100644 --- a/board/sacsng/sacsng.c +++ b/board/sacsng/sacsng.c @@ -26,7 +26,6 @@ #include #include #include -/*NO// #include */ #include #include @@ -486,9 +485,25 @@ int misc_init_r(void) } } + /* + * Stop the clocks and wait for at least 1 LRCLK period + * to make sure the clocking has really stopped. + */ + Daq_Stop_Clocks(); + udelay((1000000 / sample_rate) * NUM_LRCLKS_TO_STABILIZE); + + /* + * Initialize the clocks with the new rates + */ Daq_Init_Clocks(sample_rate, sample_64x); sample_rate = Daq_Get_SampleRate(); + + /* + * Start the clocks and wait for at least 1 LRCLK period + * to make sure the clocking has become stable. + */ Daq_Start_Clocks(sample_rate); + udelay((1000000 / sample_rate) * NUM_LRCLKS_TO_STABILIZE); sprintf(str_buf, "%d", sample_rate); setenv("DaqSampleRate", str_buf); @@ -792,10 +807,12 @@ void spi_dac_chipsel(int cs) * chip selects: it calls the appropriate function to control the SPI * chip selects. */ -spi_chipsel_type spi_chipsel[2] = { +spi_chipsel_type spi_chipsel[] = { spi_adc_chipsel, spi_dac_chipsel }; +int spi_chipsel_cnt = sizeof(spi_chipsel) / sizeof(spi_chipsel[0]); + #endif /* CFG_CMD_SPI */ #endif /* CONFIG_MISC_INIT_R */ -- cgit v1.1
