Our kernel is based off the sdk-v1.5 tag in the Freescale GIT tree. With 4GB of memory every driver worked, but with 8GB the following drivers have failed: MMC, USB, and SATA. In each case the on-chip device only supports 32-bit addressing.</P><P></P><P>I've fixed MMC by disabling DMA when the board has more than 4GB. Has anybody got USB and SATA working in large memory scenarios?</P><P></P><P>usb 1-1: device descriptor read/64, error -32</P><P>usb 1-1: device descriptor read/64, error -32</P><P>usb 1-1: new high-speed USB device number 3 using fsl-ehci</P><P>usb 1-1: device descriptor read/64, error -32</P><P>usb 1-1: device descriptor read/64, error -32</P><P>usb 1-1: new high-speed USB device number 4 using fsl-ehci</P><P>usb 1-1: device not accepting address 4, error -32</P><P>usb 1-1: new high-speed USB device number 5 using fsl-ehci</P><P>usb 1-1: device not accepting address 5, error -32</P><P>hub 1-0:1.0: unable to enumerate USB device on port 1</P><P></P><P></P><P></P><P>ata2: Signature Update detected @ 504 msecs</P><P>ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300)</P><P>ata2.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x80)</P><P>ata2: limiting SATA link speed to 1.5 Gbps</P><P>ata2: Signature Update detected @ 504 msecs</P><P>ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300)</P><P>ata2.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x80)</P><P>ata2: Signature Update detected @ 504 msecs</P><P>ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300)</P></BODY></HTML> Wed, 26 Mar 2014 10:06:06 GMT https://community.nxp.com/t5/P-Series/Running-Linux-on-8GB-P5020/m-p/304498#M1089 adriancox 2014-03-26T10:06:06Z Re: Running Linux on 8GB P5020 https://community.nxp.com/t5/P-Series/Running-Linux-on-8GB-P5020/m-p/304499#M1090 <HTML><HEAD></HEAD><BODY><P>Fixed it - in moving to our own board file a typo had disabled SWIOTLB initialisation for platform devices.</P></BODY></HTML> Wed, 26 Mar 2014 16:19:47 GMT https://community.nxp.com/t5/P-Series/Running-Linux-on-8GB-P5020/m-p/304499#M1090 adriancox 2014-03-26T16:19:47Z
