---
Changes v1 -> v2:
- move linux source code and its patches to AndesTech Github repo
- rename ae350_andestar45_defconfig to andes_ae350_45_defconfig
- change C library to uClibc
- remove OpenSSL package
- remove rootfs.cpio and rootfs.tar
- update DEVELOPERS
Changes v2 -> v3:
- specifiy branch to download from AndesTech linux repo
- change boot.cmd to extlinux.conf
- add post-build.sh for extlinux.conf to retrieve Image and DTB
- fix format and update genimage_sdcard.cfg
- update readme.txt
- add packages (python3, pylibfdt and openssl) for u-boot binman
- reorder item in DEVELOPERS

+Subject: [PATCH] Disable PIC explicitly for assembling

+This patch is necessary if the fw_dynamic load address
+is not equal to link address.
+However, they are equal currently, since we include an u-boot
+patch for preventing fw_dynamic relocation.

+Intro
+=====
+
+Andestech AE350 Platform
+
+The AE350 prototype demonstrates the AE350 platform on the FPGA.
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+  $ make andes_ae350_45_defconfig
+
+If you want to customize your configuration:
+
+  $ make menuconfig
+
+Build everything
+----------------
+Note: you will need to access to the network, since Buildroot will
+download the packages' sources.
+
+  $ make
+
+Result of the build
+-------------------
+
+After building, you should obtain the following files:
+
+  output/images/
+  |-- ae350.dtb
+  |-- boot.vfat
+  |-- fw_dynamic.bin
+  |-- fw_dynamic.elf
+  |-- fw_jump.bin
+  |-- fw_jump.elf
+  |-- Image
+  |-- rootfs.ext2
+  |-- rootfs.ext4 -> rootfs.ext2
+  |-- sdcard.img
+  |-- u-boot-spl.bin
+  `-- u-boot.itb
+
+Copy the sdcard.img to a SD card with "dd":
+
+  $ sudo dd if=sdcard.img of=/dev/sdX bs=4096
+  $ sudo sync
+
+Your SD card partition should be:
+
+  Disk /dev/sdb: 14.48 GiB, 15552479232 bytes, 30375936 sectors
+  Disk model: Multi-Card
+  Units: sectors of 1 * 512 = 512 bytes
+  Sector size (logical/physical): 512 bytes / 512 bytes
+  I/O size (minimum/optimal): 512 bytes / 512 bytes
+  Disklabel type: dos
+  Disk identifier: 0x00000000
+
+  Device     Boot Start    End Sectors Size Id Type
+  /dev/sdb1           1   4096    4096   2M  c W95 FAT32 (LBA)
+  /dev/sdb2  *     4097 126976  122880  60M 83 Linux
+
+Insert SD card and reset the board, it should boot Linux from mmc.

Here we have both:
board/andes/ae3xx
and
board/andes/ae350

ae3xx should be use for every ae3xx family(ae350 included), but for ae350 you use a specific folder.
What I see digging into ae3xx is that it is for FPGA demonstration, so I would move ae3xx directory to be name as ae3xx-fpga. Otherwise I would expect ae350(and newer parts) to be part of ae3xx.

Same goes for the defconfig, I would name it like:
andes_ae3xx_fpga_defconfig

This way we can divide the 2 typologies:
- fpga demonostration for ae3xx
- ae3xx SoC family

Otherwise you should provide a single family folder(ae3xx) compatible for both fpgas and SoCs.

Thank you

Best regards

For this naming issue, we decide to make ae3xx
explicit to have these two platform residing
in its own folder. So it would be:

board/andes/
|- {ae3xx => ae300}/
`- ae350/

If this make sense to you, I will submit PATCH v4.

It works for me.
I've checked your website and I see:
http://www.andestech.com/en/products-solutions/andeshape-platforms/

where you have:
AE300:
http://www.andestech.com/en/products-solutions/andeshape-platforms/ae300/

and AE350:
http://www.andestech.com/en/products-solutions/andeshape-platforms/ae350-axi-based-platform-pre-integrated-with-n25f-nx25f-a25-ax25/

so your solution fits perfectly since they are two very distinct platforms.

So yes please send V4 with that change.

Thank you!

Best regards
