| KotCzarny | hehe, tobin is violating rule 1f of the pm forum | 07:28 |
|---|---|---|
| KotCzarny | erm, wrong chan :) | 07:28 |
| ceene | Pali: I know you're a bit of an expert on uboot, maybe you can lend me a hand on booting SPL on a zynqmp? I'm desperate now :( | 10:04 |
| Pali | I really do not know nothing about zynqmp | 10:05 |
| ceene | maybe you know some typical reasons for SPL not to show nothing on console? I am able to run full uboot, launched by first stage boot loader provided by xilinx, so my uboot configuration is more or less ok | 10:06 |
| ceene | but SPL doesn't even say hello on the serial port | 10:06 |
| ceene | zynqmp is quite complex indeed, having another processor to manage internal power and things, which requires an additional firmware, etc, but I would expect getting the basic "U-boot SPL" message should be pretty straightforward | 10:08 |
| KotCzarny | maybe its not booting at all? | 10:15 |
| KotCzarny | ie. crashing in spl already | 10:15 |
| ceene | probably | 10:15 |
| ceene | I think there's some way to debug this via JTAG, but xilinx tools are terrible | 10:16 |
| ceene | so it's possible I could run SPL step by step, but I'm pretty sure it has to be some configuration option that I'm not setting, or setting, or erroneously setting | 10:16 |
| Pali | I do not know... on n900 we do not use SPL at all | 10:19 |
| ceene | yeah, I've seen latests mails on the mailing list. I think they want you to | 10:20 |
| ceene | I was hoping you knew everything :) | 10:20 |
| Pali | and other platforms which I use (kirkwood/mvebu) can print to uart at early beginning | 10:20 |
| Pali | bascially the first instruction can be write to uart register and it immediately show at serial console | 10:21 |
| Pali | so if your platform has already initialized uart you may try to put debug message at early beginning if you see it... | 10:21 |
| Pali | and on arm64 I'm not using SPL too... direct U-boot loading by TF-A (arm trusted firmware) | 10:23 |
| Pali | so I do not have too much experiences with SPL | 10:23 |
| ceene | well thanks anyhow | 10:44 |
| ceene | i'll be trying a couple of things and then i'll see if i can debug this via jtag, but i'm not sure if it's possible | 10:45 |
