Indeed you need to write fip/u-boot.bin at the second block (512bytes)

@TonyMac32I found a regression, can you test this fix ? https://github.com/superna9999/linux/commit/b9edb9c9eec654ba57f8da7966e4b1b81a6d7c7b

We plan to use https://github.com/superna9999/pyamlboot for LaFrite, but it works on LePotato aswell, and it will be supported by the next U-boot version (in master right now https://github.com/u-boot/u-boot/commit/d96a782d09dbdc4a28ece3d18dc17a572e39d4f2)
We still need to generate a generic initramfs+kernel image to flash anything.

@Tommy21 No need to wait, it already works

@TonyMac32 Here is a fix : https://lore.kernel.org/patchwork/patch/949665/

@TonyMac32 yeah, I know this one, and I need to solve it. Hopefullyt it won't harm, it's just a warning I need to solve and find time to solve it...

Hi @TonyMac32 this patch will solve the issue on 4.17 and 4.18-rc3 :
https://patchwork.kernel.org/patch/10462135/
it should be merged for -rc4 and hopefully be backported to 4.17 next week

The wakeup from power-off is indeed managed by the Cortex-M processor with some code loaded in the boot time.
This code can be modifier and is present in amlogic's u-boot source :
https://github.com/BayLibre/u-boot/blob/n-amlogic-openlinux-20170606/board/amlogic/gxl_p212_v1/firmware/scp_task/pwr_ctrl.c#L184
 
But, it's linked to the Amlogic kernel implementation, and supporting it with mainline linux will need some work.

@TonyMac32 It's not an issue, u-boot will cycle over all mmc interfaces, numbers are unrelated, mmc0 is the first mmc interfaces, on Potato it's the SDCard.

Hi @TonyMac32
 
I just pushed a 4.16 patchset : https://github.com/superna9999/meta-meson/tree/master/recipes-kernel/linux/linux-yocto-meson64-4.16
 

These names should be printed in the /sys/kernel/début/gpio if not there must be a mismatch in the number of entries.
 
can you dump the dmesg somewhere ?
 
Here is a sheet of all the pins exported by the potato board https://docs.google.com/spreadsheets/d/1uu09Fp14bJ9YhlEIYVn5R430V4p-v6A4SsAgdEem9EI
 
To know the gpio number, the first bank with 10 gpios is the AO bank from GPIOAO_0 to 9.
the second bank mapping can be found in the kernel header : https://github.com/torvalds/linux/blob/master/include/dt-bindings/gpio/meson-gxl-gpio.h

Good, please tell me if an issue appears with this patchset ! I cleaned it up because it was insane !

Hi,
 
Mainline Linux has support for the SCPI Temperature Sensor, please check in /sys/class/hwmon/hwmon0/temp1_input
 
For the hard crash, looking at the logs seems to indicate a memory issue, we will investigate further !
 
Thanks,
Neil
