Re: [beagleboard] Want to serial boot my BBB
uboot is supposed to handle serial booting. However, I have no personal hands on. Just a quick google search showed many results however. One thing to note is that uboot for the BBB is patched, so possibly different. It does not however make sense for this feature to be patched out, so I would assume that it should work. Sorry for the less than definitive answer, perhaps someone with hands on will respond. You can however experiment on your own. http://blackfin.uclinux.org/doku.php?id=bootloaders:u-boot:serial_port_loading_files http://blog.mezeske.com/?p=483 $ apt-cache search ckermit ckermit - serial and network communications package Second link package mentioned is available, so looks to be possible.

Re: [beagleboard] Want to serial boot my BBB
Ok after reading the second link fully, I noticed a few things. First, the boot file is different. We have zImage typically, so I would assume the bootz command would be necessary. *OR* you could convert a zImage to uImage. Secondly, the base load address is different, so this would need to be taken into account. Although I think changing this would be fairly simple. Lastly, we also need to load the device tree board file, and I am a bit confused about this for loading serially.

Re: [beagleboard] Want to serial boot my BBB
Hi William. Thanks for the help. I'm stuck much earlier on than u-boot. I am expecting the ROM to return the ASIC ID when I run the pserial command to try and load the first stage boot loader (x-load.bin). I'm not even able to get past that. It looks like either I have the wrong pserial command or maybe the BBB ROM does not provide an ASIC ID. I don't know enough about the Sitara processor to say. If I can get the x-loader to work, I think I am home free because it should be able to load a u-boot.bin.

Re: [beagleboard] Want to serial boot my BBB
One other data point. If I don't press and hold the boot switch when power is applied and instead wait a few seconds after applying power and then press the boot switch, the pserial command is able to detect the ASIC ID and download the x-loan.bin. $ sudo ./pserial -p /dev/ttyUSB0 -f x-load.bin Waiting For Device ASIC ID: Press Ctrl+C to stop ASIC ID Detected: 0x85 0x74 0x61 0x90 Sending 2ndFile: Downloading file: 100.000% completed (10516/10516 bytes) File download completed. However, the BBB boots from the eMMC instead of the x-loan.bin I downloaded. So this is progress. It means that my pserial command does work with a BBB and the BBB ROM code does respond with its ASIC ID and does in fact download the x-load.bin. It looks like I just need to figure out what the correct boot switch power on sequence is now. On Sunday, July 20, 2014 10:36:45 AM UTC-5, Dallas Clement wrote: > > Hi William. Thanks for the help.

You should be loading MLO, not x-load.bin. I also haven¹t tried this myself, but loading via serial shouldn¹t be any different from loading from tftp. The load addresses should be identical.

Re: [beagleboard] Want to serial boot my BBB
If I remember correctly , You should load x-loader.bin NOT MLO While the different between MLO and x-loader.bin is MLO has 8 bytes head , the first 4 bytes is dest and the second 4 bytes is length . This is for boot from NAND /eMMC , and when download from serial . the boot rom will download to fixed address and limit length . 2014-07-21 12:04 GMT+08:00 John Syn : > > From: Dallas Clement > Reply-To: "beagleboard@googlegroups.com" > Date: Sunday, July 20, 2014 at 9:19 AM > To: "beagleboard@googlegroups.com" > Subject: Re: [beagleboard] Want to serial boot my BBB > > One other data point.

Re: [beagleboard] Want to serial boot my BBB
Sorry , I have made a mistake . On omap3 board ,you should use pserial to download from serial And on am335x / dm8148 board. x-modem is enough.and MLO is for boot from serial So , please try to use teraterm , and upload from file->transfer->xmodem->send. Then power on the beaglebone board . 2014-07-21 16:17 GMT+08:00 liyaoshi : > If I remember correctly , You should load x-loader.bin NOT MLO > While the different between MLO and x-loader.bin is MLO has 8 bytes head , > the first 4 bytes is dest and the second 4 bytes is length . > This is for boot from NAND /eMMC , and when download from serial . the > boot rom will download to fixed address and limit length . > > > > 2014-07-21 12:04 GMT+08:00 John Syn : > > >> From: Dallas Clement >> Reply-To: "beagleboard@googlegroups.com" >> Date: Sunday, July 20, 2014 at 9:19 AM >> To: "beagleboard@googlegroups.com" >> Subject: Re: [beagleboard] Want to serial boot my BBB >> >> One other data point.

I was able to send the MLO file via minicom / x-modem just fine to the board. However after the transfer completed, nothing happened.

Re: [beagleboard] Want to serial boot my BBB
For UART or USB you do not use the MLO file. When you build u-boot you should have a spl/u-boot-spl.bin file. This is what you send over x-modem. The MLO file is only used for Memory Booting (SD/Card, eMMC) while the u-boot-spl.bin file is used for Peripheral Booting (UART, USB). Steve K.

My understanding is that u-boot cannot be loaded directly because it is too big to fit into the SRAM, so MLO is loaded into SRAM which then sets up the DDR memory and timing and then u-boot is loaded into DDR memory. Why should this be any different when using UART or USB? Do you have any docs that explains the difference?
