I studied the pinephone_defconfig. By default, when activating the same options on Cubieboard2_defconfig it shows linker error for `__led_init` and `__led_set`. In other words, they are not defined. So, in this patch, I added the implementation for these functions for this board. Regards, Javad > > > Gesendet: Mittwoch, 08.

That's probably our old friend .bss in SPL again: To save precious SRAM space, we place the BSS section in DRAM, so it's only available after the DRAM init happened. So far the code that runs before DRAM init is not using variables placed in BSS, so everything works. Possible solutions are: 1) see if we can get rid of BSS variables in the LED code (my bet is on "static int status_led_init_done = 0;" as the culprit) 2) move the LED init after the DRAM init. That's probably a bit late, though, depends a bit on what people expect from the boot LED. 3) I guess the A20 can afford BSS in SRAM, but that would not help with other (64-bit) boards. I actually wonder how it works there, though? I'd prefer 1), but 2) is surely easier.

I removed this variable and added a one-bit variable named "initialized" to the `led_dev_t ` . In this case, when `__led_init` is called, we can set it for every single LED. In this case, we can check `ld->initilized` for each led rather than blindly checking the `status_led_init_done` global variable.

Interesting idea, though I don't know too much about this code, and why we had the global variable in the first place. Can you prepare a patch and send it to the mailing list, so that people can have a look and discuss this?
