TI811X+JAMR2 daughter card
- I2C errors will thrown if JAMR2 daughter card is connected to the EVM and not powered up correctly.
PCIe: - PCIe is not supported.
- sbuffaddr is 0x9fd00000 for releases till HDVPSS_01_00_01_43. From HDVPSS_01_00_01_44 release onwards the sbuffaddr is changed to 0x9fb00000.
- Make sure that PIN8 of SW6 switch is turned on(to make off-chip HDMI display and EVM LCD display work).
- For Off-Chip HDMI display, on some TV's the image might be cropped(Few Lines(~15) on left and top might be missed), This is due to some TV's will do overscaling.If TV supports to disable this feature, then after disabling the video will be proper.
- Some Flashes will be seen on LCD display during power cycle. After inserting tlc59108 module, you will see Flickers, change the venc timings suitable for LCD.Refer Video Driver User Guide for more details on changing the timings.
- Off-Chip HDMI is working with only small lilliput display, samsung and philips TV, some models of Samsung may not work.
- Flickers observed on LCD display while booting. This is due to some bug in the LCD daughter board.The fix for this issue is Removing R23 from the LCD daughter board.
Hardware modification for Off-Chip HDMI to work with all TV's
Remove R267 and R578, and populate R264 and R579 with 10K registers
Hardware modification for Flickers observed on LCD display while booting
Removing R23 from the LCD daughter board.
Hardware modification for 16-bit NAND/NOR
16-bit NAND is supplied with the EVM but the bus width selection switch is not populated on the EVM. By default, GPMC_D is pulled down, hence corresponding to 8-bit NAND support. So, to support the NAND boot on the EVM (having 16-bit NAND), the following modification has to be done:
- Pull up GPMC_D: the resistor populated at R336 should be moved to R313
This will set BTMODE12 to 1, which is the required configuration to support 16-bit NAND.
USB Overcurrent on USB1 port:
Please use daughter board for USB1 support, refer to TI811X known issue section.
- GPIO ports from banks 4 and 5 do not have any pin control registers associated with them and hence were not added to pinmux table.
- GPIO banks 4 and 5 do not have direct interrupt lines. For details on configuring GPIO interrupts refer to Confguriing Interrupts for GPIO4 and 5 Banks
Ethernet Switch setting
Ethernet Pins and GPMC (NOR) pins are muxed in the EVM. The mux selection can be done via combination of EVM switch setting and GPIO(Bank-5 GPIO-4).
- GP5 is by default low and not programmed
|SW10.2||GPMC/EMAC Pinout connects to|
EMAC 1 Phy power line is connected via SW7.1, to enable EMAC 1 Phy the following setting to be followed
- SW7.1 - On
CPSW Switch configuration
- Swtich configuration IOCTL command interface is changed from SIOCDEVPRIVATE to SIOCSWITCHCONFIG.

This list of known issues for this release
|Issue Identifier||Issue Headline||Known Workaround(s)|
||Audio pop noise while powering up the codec..||This is due to the AIC3106 Codec hardware limitation.|
||USB: : In OTG/dual role mode, after removal of all the devices connected to root port and again re-connect of device does not get detect.|| Since usb is built in otg mode, this is expected behavior in real usb otg mode functionality. The workaround is to set the session bit after re-connect of device (use command # echo F > /proc/driver/musb_hdrc.0 or 1) |
|| USB: Sequence to be followed while rmmod of musb driver module in loop
||Insert the musb modules in sequence (1. musb_hdrc.ko, 2.cppi41dma.ko, 3.ti81xx.ko) and remove all the modules in reverse order of insertion.|
|SDOCM00087448||USB_Audio : DUT hangs for 8 to 10 sec when unpluging the USB audio device during playback||Issue observed while using aplay utility, the aplay application does not exit after device disconnect. Recommended to stop the audio playback before unplugging of audio device.|
|SDOCM00088375||USB: Truncated packets with CRC error observed during transmit operation causing multiple resets while creating a file on HP flash drive||The requires both (a) following the TI recommended USB PCB Design guideline and (b) SW workaround to fine-tune USBPHY calibration parameters. The SW patch is available as part of release package.|
|SDOCM00091461||USB: CPPI41DMA: TX DMA generates the early completion interrupt before last byte from endpoint TxFifo is transferred out.||SW workaround is to poll till last byte is transferred out on bus, the patch available as part of release package.|
|SDOCM0086738||Extra IN token issue: While transferring file through usb-wifi client(to tftp server) & concurrent i/o to connected USB HDD, causes intermittent resets on the USB bus||SW workaround is to configure the rx transfer in transparent DMA mode and handle USB data toggle appropriately. The workaround is included in the release package|
|SDOCM0091179||USB: MUSB spurious interrupt observed during Isochronous transfer. The PID/CRC errors interrupts gets cleared by USB DMA before CPU could read error status, thus making the interrupt spurious.||No workaround. Though CRC errors of Isochronous does not impact functionally, this prevents application to take any further action in case of very bad USB signal quality.|
|SDOCM00086741||USB: While performing USBCV test with Remote wake-up capability(rndis) the EVM console freezes till test is completed.||None|
|SDOCM00096335||USB: feeble, momentary audio glitch observed when new device inserted while playing audio out through usb headset||None|
|| USB: Dynamic detection of USB-ID pin not working when device connected after linux bootup
||Configure USBx_ID pin appropriately for host/device role. USBx_ID pin to Short (for host mode) and open (for device mode).|
|| USBOTG: The SRP (Session Request Protocol) initiated from OTG-B peripheral device is not working
|SDOCM00089115||NAND: Subpage support in NAND is not implemented||None|
|| NAND: 1-bit data corruption observed while running stress test
|SDOCM00090415||There is continuous over current message on console from USB1 port when kernel loaded in usb host mode on EVM||If daughter board or USB1 port is not used, then disable the USB1 port, follow the steps explained in this patch. Note that this patch will not apply directly, edit the specific changes manually as mentioned in the patch.|
|SDOCM00093550||Connecting USB mouse post boot does not work||Need to ensure that the mini-A-cable shipped with the kit is left connected at all times. Hot plugging devices will then work.|
|SDOCM00093551||/proc/cpuinfo shows incorrect value(value 0) for revision and Serial no||None|
|SDOCM00091706||[HDVPSS-HDMI] HDMI Control STOP on Disabled HDMI output causes HDMI driver to crash||None|
|SDOCM00092874||[HDVPSS] ioctl VIDIOC_S_CROP fails||The scalar component present in the VIP module will not pass the FID (field id) information (it will always send the field id as 0, for all the fields). This IOCTL will configures the frame resolution of the output of sclar. As scalar cannot be used for interlaced content, this IOCTL is not supported.|
|SDOCM00092875||ioctl VIDIOC_S_FMT with buf type V4L2_BUF_TYPE_VIDEO_OVERLAY fails||The scalar component present in the VIP module will not pass the FID (field id) information (it will always send the field id as 0, for all the fields). This IOCTL will configures the frame resolution of the output of sclar. As scalar cannot be used for interlaced content, this IOCTL is not supported.|
|| MMC write protection is not working. Card is writable even if it is locked
|| This is limitation on the EVM as the write-protect pinis not hooked up. Software ignores the write protect status of the card|
||Ethernet PHY (on port 0) doesn't get detected after 80 plus (soft)reboots||The issue is seen with only one of the ports on the J5Eco EVM|
||MMC Module is not prevented from being removed.While an IO operation is in progress, the MMC module is still being permitted to be removed.||Limitation with the MMC stack on Linux|
||MMC modular stress read write test fails on some cards. The issue is seen with specific cards on subsequent insmod operations(after rmmod)||Use MMC driver as kernel built-in|
||Removing SPI controller module during SPI flash read/write causes failures||Use SPI controller driver as kernel built-in|
||NAND: modular stress test cause kernel crash||Use Nand driver as kernel built-in|
- VIDIOC_QUERYSTD on capture device is not supported. This is software limitation, because TVP5158 is not added as sub-device.TVP5158 driver need to be enabled in video capture driver to support this.
- DVI support for sii9022a driver is not supported If the Display monitor is in DVI mode then cropping happens as sii9022a driver is not supported.
- IOCTL VIDIOC_S_CROP and VIDIOC_S_FMT with buf type V4L2_BUF_TYPE_VIDEO_OVERLAY is not supported if the input format is interlaced.The scalar component present in the VIP module will not pass the FID (field id) information (it will always send the field id as 0, for all the fields).This IOCTL will configures the frame resolution of the output of scalar. As scalar cannot be used for interlaced content, this IOCTL is not supported.
