    Hello, McASP as master is not supported currently. If you want to try this out here are a couple of pointers... 1. davinci-evm.c- Change the AUDIO_FORMAT macro to reflect codec is the slave a) #define AUDIO_FORMAT (SND_SOC_DAIFMT_DSP_B | \ SND_SOC_DAIFMT_CBS_CFS | SND_SOC_DAIFMT_IB_NF b)...

    Vaibhav Bedia
    1st stage U-Boot bootcmd is meant to be hardcoded. From the U-Boot user guide- "The boot command that the minimal U-Boot uses for fetching the larger U-Boot will not change for a particular boot mode as long as the same layout is used and is hence fixed. If any other behavior required then...

    Hi all, are there any schedules when hdmi audio will be available on the dm8148 evm? The latest PSP (04.01.00.05.patch1) states this still as unsupported. Thanks and regards, Bernhard

    Vaibhav Bedia
    You need to specify the complete path. So this Eric Chen export PATH=/CodeSourcery/Sourcery_G++_Lite/bin:$PATH should be export PATH= /eric /CodeSourcery/Sourcery_G++_Lite/bin:$PATH and so on. Eric Chen is building U-Boot in Linux the only way to make image of code written to storage...

    Hi Steve, Yes, you can read the GPIO pin status from u-boot. Steps for reading the GPIO pins:- 1. Enable clock for GPIO bank which you are using. 2. Put the GPIO pins in Input mode 3. Read the register values to know the status Regards AnilKumar

    Hello, Delio Brignoli Is there a technical reason for not supporting the same feature on TI814X? As you rightly pointed out, Initial versions of 1st stage of U-Boot for TI8148 did run out of internal RAM. However, when adding SD boot support we realized that the buffers that the driver uses...

    Nageswari Srinivasan
    Hi, DMA mode is currently not supported in the DM814x serial driver even though it uses omap-serial driver. (DMA is currently switched off for DM814x). Default OMAP serial driver uses SDMA (OMAP3 DMA) to implement DMA functionality. (drivers/tty/serial/omap-serial.c) But DMA engine is different...

    Hi, If you haven't done so already, there's one thing that i think you can try... set all the other muxed modes of UART4_RXD (PINCTRL168, 209 and 251) to 0xF0000. This would disable the internal pulls on these pins. Regards, Vaibhav

    Christian, There is no difference apart from DM8148 having x1 and DM8168 having x2 link width. Can you provide more information such as logs (refer Root Complex Driver User Guide), lspci -xvv output on both setups , what is the driver for endpoint you are loading?

    Christian, There should not be any difference on MSI. Regarding DMA, is this DMA from Endpoint or EDMA from DM816x/DM816x device? While I try to replicate the scenario (using an off the shelf card), can you use legacy interrupt for the time being (the Lancero driver needs to support this) ?...

  • Forum Post: Re: PCI root complex differences between DM8148 and DM8168 ?

    HemantPedanekar
    Christian, Ok, so at least legacy interrupts work. I will try with a card supporting MSI to check if this could be some s/w issue like incorrect interrupt number being used or EOI requirement. Hemant

  • Forum Post: Re: PCI root complex differences between DM8148 and DM8168 ?

    HemantPedanekar
    An update: I think the issue is with difference in clearing the MSI interrupt across DM816x and DM814x (as you guessed). In file arch/arm/mach-omap2/pcie-ti81xx.c, change the following line in function ack_msi() --> __raw_writel(~(1 << (msi_num & 0x1f)), reg_virt + MSI0_IRQ_STATUS...

    Leon, I will get back with concrete answer on the further differences question in a day or two. Meanwhile, regarding the interrupt ack behavior, I am still verifying the modifications suggested earlier, but if confirmed, yes, it will be due to the difference in PCIe h/w versions being used in DM8168...
