* imx-image: mx35: increase load image size, due to dobule headerMarc Kleine-Budde2015-04-031-0/+3
| | | | | | | | | | | | | Since commit: 690e39202747 imx-image: handle i.MX35 special case the IVT+DCD header is placed both at 0x0 and 0x1000, this patch reflects this change and increases the load image size accordingly.

* imx-image: handle i.MX35 special caseEric Bénard2014-09-251-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From the i.MX35 user manual : Since MLC NAND Flash devices do not guarantee error-free boot blocks, the i.MX35 boot code requires that the first 4 Kbytes of boot code be duplicated in a subsequent block to serve as a second copy option. Actually imx-image puts the image at 4k but it seems that the i.MX35 bootrom copies only from 8k as it expects that there is a copy of the first 0-4k in 4k-8k (and is supposed to use this copy if there is an ECC error in the first 4k) as we can see in the following lines : barebox@Eukrea CPUIMX35:/ md -s /dev/nand0 0x0 00000000: ea0003fe eafffffe eafffffe eafffffe ................ 00000010: eafffffe eafffffe eafffffe eafffffe ................ 00000020: 65726162 00786f62 00000000 00000000 barebox......... =-> header is @ 0 in flash barebox@Eukrea CPUIMX35:/ md -s /dev/nand0 0x1000 00001000: 56341200 00000000 0001eda1 00000000 ..4V............ 00001010: 00000000 00000000 00000000 00000000 ................ =-> so we have data @ 0x1000 in flash barebox@Eukrea CPUIMX35:/ md 0x87f00000 87f00000: 00000000 00000000 00000000 00000000 ................ 87f00010: 00000000 00000000 00000000 00000000 ................ =-> but we don't find this data in RAM barebox@Eukrea CPUIMX35:/ md -s /dev/nand0 0x2000 00002000: ea000012 eafffffe eafffffe eafffffe ................ 00002010: eafffffe eafffffe eafffffe eafffffe ................ 00002020: 65726162 00786f62 00000000 00034272 barebox.....rB.. =-> so we have the image @ 0x2000 in flash barebox@Eukrea CPUIMX35:/ md 0x87f01000 87f01000: ea000871 eafffffe eafffffe eafffffe q............... 87f01010: eafffffe eafffffe eafffffe eafffffe ................ 87f01020: 65726162 00786f62 87f02000 0003b520 barebox.. .. ... =-> and we find it in RAM Signed-off-by: Eric Bénard <eric@eukrea.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* imx-image: Handle check commands correctlySascha Hauer2014-09-191-21/+15
| | | | | | | | The length of two subsequent check commands was incorrectly calculated. The check commands have a fixed length anyway, so program a fixed length in the check command and skip the code from check_last_dcd. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* scripts: imx-image: Add i.MX25 supportSascha Hauer2013-11-271-0/+1
| | | | | | | The i.MX25 works like the i.MX51, just add the SoC magic and the USB product id. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* imx-image: Align image sizeSascha Hauer2013-08-151-3/+13
| | | | | | | Several boot modes on i.MX can't cope with partial pages or non word aligned image lengths, so align the size to 4k. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* scripts: imx-image: allow semicolon as command delimiterSascha Hauer2013-07-221-5/+34
| | | | | | | | | When we want to pass the imxcfg files through cpp we also want to allow defines which define multiple commands. For this to work we have to use an additional command delimiter as we can't pass '\n' though cpp. Use ';' for this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* scripts: Add imx-usb-loader toolSascha Hauer2013-05-311-0/+744
This adds host tools for i.MX to generate the i.MX internal flash header format and a tool to upload these images to an i.MX SoC via USB. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
