| 09:14 | topi`> | jnettlet[m]: we have one usbA-usbA cable that we use for flashing, and I'm not sure it won't break after 100 uses |
| 09:15 | topi`> | of course someone can fix it, but we cannot solder in our current offices. It's a bugger |
| 09:16 | topi`> | compiling buildroot with 4.9.13 kernel... I added a patchset that should enable som-v15 dts and stuff. |
| 09:29 | jnettlet[m]> | topi`: with the Rev 1.4 boards you don't need to fuse the boot mode any longer. You can use the jumpers to choose the boot medium. So you can boot an unfused som from SDHC and flash from that. |
| 09:49 | topi`> | yeah that's cool |
| 09:49 | topi`> | have you tested that it works as intended? :) |
| 09:55 | topi`> | damn I've forgotten how to embed the rootfs.tar into zImage when building a buildroot |
| 09:56 | topi`> | my previous buildroot builder went into dev/null when I accidentally deleted the wrong VPS |
| 09:56 | topi`> | without backups... |
| 09:56 | suihkulokki> | kauaksi pilvet karkasivat |
| 10:29 | topi`> | simply choosing "Initial RAM filesystem linked into linux kernel" from buildroot's config won't integrate rootfs.cpio into zImage, but just creates it in outputs/images |
| 10:29 | topi`> | :( |
| 10:30 | topi`> | I want a big fat zImage so that it can be loaded with the imx_usb_loader in one go |
| 10:48 | topi`> | I'll just try a global rebuild of buildroot... make clean and then wait, wait, wait |
| 10:49 | bencoh> | "in one go"? |
| 10:52 | topi`> | bencoh: because imx_usb_loader directly loads&boots an zImage, I cannot include other files, like a separate rootfs.cpio |
| 10:53 | topi`> | so rootfs has to be integrated inside zImage |
| 10:54 | bencoh> | why don't you make it load uboot to chainload everything? |
| 10:55 | bencoh> | (imx_usb can load different files in memory) |
| 10:56 | topi`> | OK so uboot can also be loaded? |
| 10:56 | bencoh> | sure |
| 10:56 | topi`> | but I already got the buildroot to make an integrated huge zImage, so I know it works |
| 10:57 | topi`> | I just need to remember what configs I had to make buildroot use |
| 10:57 | vpeter> | topi`: Maybe useful https://community.nxp.com/thread/441563 |
| 10:59 | jnettlet[m]> | well if you want to flash over a usb-otg cable then you can just use dfu |
| 10:59 | bencoh> | that to, assuming uboot enables/runs dfu |
| 10:59 | jnettlet[m]> | well you just need to build u-boot to do it. |
| 11:00 | topi`> | wow, now I have an integrated zImage |
| 11:00 | topi`> | I needed to "make clean" the entire buildroot project |
| 11:00 | bencoh> | and have run dfu commands to configure and start it, but yeah |
| 11:00 | topi`> | I don't know dfu |
| 11:00 | bencoh> | s/have/have uboot/ |
| 11:00 | topi`> | I stick to the old known stuff :) |
| 11:00 | jnettlet[m]> | dfu is old |
| 11:00 | jnettlet[m]> | built by nokia for the 770 :) |
| 11:00 | bencoh> | :) |
| 11:01 | topi`> | oh, THAT dfu |
| 11:01 | bencoh> | (nokia NIT <3) |
| 11:01 | jnettlet[m]> | yes, it has finally been integrated into u-boot after all this time. |
| 14:16 | topi`> | does anyone know if there are IP65 enclosures available for Hummingboard? |
| 15:13 | jnettlet[m]> | topi`: we have designed a few for other customers. contact Ilya and see if you can use one of them. |
| 19:04 | topi`> | jnettlet[m]: can we have 2 mPCIe-connected usb devices on the HB? probably not... |
| 19:05 | topi`> | perhaps would work on the ClearFog if the M.2 slot can be repurposed for a wifi card |
| 19:05 | topi`> | dunno if the A38x serdes lines are as flexible as on the 8040? |
| 19:06 | jnettlet[m]> | The CF base supports that for the m.2 slot but the connector we use is generally only used for sata and lte modems |
| 19:07 | jnettlet[m]> | That m.2 slot supports sata, USB 3, and USB 2 |
| 19:22 | topi`> | which key is that? |
| 19:22 | topi`> | most wifi cards seem to be A- or E-keyed |
| 19:37 | jnettlet[m]> | key B I believe. It is on the schematic |
