FRWY-LS1012A qspi access and ethernet problem

[gyosunshim]

Hello,

I am using a FRWY-LS1012A custom board.

QSPI is  mx25u25645g and eth phy is the same AR8033.

I ported LSDK18.12, but there is a problem with qspi control and Ethernet operation.

After building, the firmware_ls1012afrwy_uboot_qspiboot.img file was written to QSPI using an external MCU.

1. QSPI access problem on u-boot

If I do saveenv, I get a fail.

I tried adding the ID to vi drivers/mtd/spi/spi_flash_ids.c, but it doesn't seem to be recognized.

/*{"mx25u25635f", INFO(0xc22539, 0x0, 64 * 1024, 512, RD_FULL | WR_QPP) },*/
{"mx25u25645g", INFO(0xc22539, 0x0, 64 * 1024, 512, RD_FULL | WR_QPP) }, /* new */

=> saveenv
Saving Environment to SPI Flash... SF: unrecognized JEDEC id bytes: c2, 25, 39
*** Warning - spi_flash_probe() failed, using default environment

Failed (-5)
=>

2. Cannot create ethernet interface after booting

The default ubuntu rootfs is heavy, so I tested two rootfs as shown below.

2.1 flex-builder -i mkrfs -r ubuntu:tiny -a arm64

When ubuntu:tiny rootfs is booted, it will no longer proceed as shown below.

...

[ OK ] Started Getty on tty1.
[ OK ] Reached target Host and Network Name Lookups.
[ OK ] Started Dispatcher daemon for systemd-networkd.
[*** ] A start job is running for dev-ttyS0.device (21s / 1min 30s)

2.2 flex-builder -i mkrfs -r debian:tiny:stretch -a arm64

debian:tiny:stretch rootfs is logged on but the ethernet interface is not created.

Hi yipingwang,

After adding CONFIG_SPI_FLASH_MACRONIX to ls1012afrwy.h, it was confirmed that it is recognized normally.

And the second pfe driver problem was solved by unpacking the  linux_lib_firmware_LS_arm64.tgz to the /lib/firmware folder.

Thanks for the help.

Best Regards,

Gyosun.

[yipingwang · Accepted solution]

1. Please define CONFIG_SPI_FLASH_MACRONIX in include/configs/ls1012afrwy.h in u-boot source code.

2. I uploaded tiny image built from LSDK 18.12 release in the following link.

https://drive.google.com/file/d/1P-tuGgYeBZmscex2PRm5WdAzSBokAvaP/view?usp=sharing

Please run the following command to check whether pfe driver sets up successfully.

=> tftp 0xa0000000 nxa22585/ls1012afrwy/lsdk_linux_arm64_LS_tiny.itb

=> bootm 0xa0000000#ls1012afrwy
