[U-Boot] arm: imx: Kernel not booting when environment is in QSPI
Hi
I work with an imx6sx sdb. I observed that placing u-boot in QSPI flash and also having the environment in QSPI the linux kernel doesn't boot. The backtrace from the kernel contains 'fsl_qspi_probe'. If only u-boot resides in QSPI and the environment is on mmc then the kernel boots successfully.
Some more investigation showed that even when u-boot and the environment is on mmc a simple => sf probe 1:0 causing the kernel not to boot.
So I suspect a problem with u-boot not leaving the QSPI hardware in a sane state for the kernel driver to take over control. If no serial flash operations are executed in u-boot I can access the flash in linux via mtd.
Kernel and u-boot are both current git HEAD with minor changes. Anyone with an idea?
Regards Matthias

Hi
I work with an imx6sx sdb. I observed that placing u-boot in QSPI flash and also having the environment in QSPI the linux kernel doesn't boot. The backtrace from the kernel contains 'fsl_qspi_probe'. If only u-boot resides in QSPI and the environment is on mmc then the kernel boots successfully.
Some more investigation showed that even when u-boot and the environment is on mmc a simple => sf probe 1:0 causing the kernel not to boot.
So I suspect a problem with u-boot not leaving the QSPI hardware in a sane state for the kernel driver to take over control. If no serial flash operations are executed in u-boot I can access the flash in linux via mtd.
Kernel and u-boot are both current git HEAD with minor changes. Anyone with an idea?
Regards Matthias

Hi
I work with an imx6sx sdb. I observed that placing u-boot in QSPI flash and also having the environment in QSPI the linux kernel doesn't boot. The backtrace from the kernel contains 'fsl_qspi_probe'. If only u-boot resides in QSPI and the environment is on mmc then the kernel boots successfully.
Some more investigation showed that even when u-boot and the environment is on mmc a simple => sf probe 1:0 causing the kernel not to boot.
So I suspect a problem with u-boot not leaving the QSPI hardware in a sane state for the kernel driver to take over control. If no serial flash operations are executed in u-boot I can access the flash in linux via mtd.
Kernel and u-boot are both current git HEAD with minor changes. Anyone with an idea?
Regards Matthias

Adding Allen,
Hi Matthias,
I can not reproduce your issue. All is fine in my side.
which version/branch are you using for uboot and linux? mainline or fsl vendor?
Regards, Peng.

Hi
I work with an imx6sx sdb. I observed that placing u-boot in QSPI flash and also having the environment in QSPI the linux kernel doesn't boot. The backtrace from the kernel contains 'fsl_qspi_probe'. If only u-boot resides in QSPI and the environment is on mmc then the kernel boots successfully.
Some more investigation showed that even when u-boot and the environment is on mmc a simple => sf probe 1:0 causing the kernel not to boot.
So I suspect a problem with u-boot not leaving the QSPI hardware in a sane state for the kernel driver to take over control. If no serial flash operations are executed in u-boot I can access the flash in linux via mtd.
Kernel and u-boot are both current git HEAD with minor changes. Anyone with an idea?
Regards Matthias

Hi Peng
I use mainline (current HEAD, u-boot 2015.07-rc2, linux 4.1.0-rc7) on both sides.

Hi Matthias,
I can not reproduce your issue. All is fine in my side.
which version/branch are you using for uboot and linux? mainline or fsl vendor?
Regards, Peng.

Hi
I work with an imx6sx sdb. I observed that placing u-boot in QSPI flash and also having the environment in QSPI the linux kernel doesn't boot. The backtrace from the kernel contains 'fsl_qspi_probe'. If only u-boot resides in QSPI and the environment is on mmc then the kernel boots successfully.
Some more investigation showed that even when u-boot and the environment is on mmc a simple => sf probe 1:0 causing the kernel not to boot.
So I suspect a problem with u-boot not leaving the QSPI hardware in a sane state for the kernel driver to take over control. If no serial flash operations are executed in u-boot I can access the flash in linux via mtd.
Kernel and u-boot are both current git HEAD with minor changes. Anyone with an idea?
Regards Matthias

Hi Peng
With some wild guessing I found out that it must be an interrupt issue. If I clear FR (offset 0x160) in the QSPI module using u-boot command Linux boots successfully. So it seams that u-boot should clear the interrupt flag of the QSPI module after it was used.
Commands used to clear the flags:
=> md 0x021e4160 1 021e4160: 08010001 .... => mw 0x021e4160 0x08010001
I then added clearing FR in qspi_xfer
diff --git a/drivers/spi/fsl_qspi.c b/drivers/spi/fsl_qspi.c index 868df5f..cb67f98 100644 --- a/drivers/spi/fsl_qspi.c +++ b/drivers/spi/fsl_qspi.c @@ -765,6 +765,9 @@ int qspi_xfer(struct fsl_qspi_priv *priv, unsigned int bitlen, qspi_ahb_invalid(priv); #endif
+ qspi_write32(priv->flags, &priv->regs->fr, + qspi_read32(priv->flags, &priv->regs->fr)); + return 0; }
This works for me.

Hi Matthias,
I can not reproduce your issue. All is fine in my side.
which version/branch are you using for uboot and linux? mainline or fsl vendor?
Regards, Peng.

Hi
I work with an imx6sx sdb. I observed that placing u-boot in QSPI flash and also having the environment in QSPI the linux kernel doesn't boot. The backtrace from the kernel contains 'fsl_qspi_probe'. If only u-boot resides in QSPI and the environment is on mmc then the kernel boots successfully.
Some more investigation showed that even when u-boot and the environment is on mmc a simple => sf probe 1:0 causing the kernel not to boot.
So I suspect a problem with u-boot not leaving the QSPI hardware in a sane state for the kernel driver to take over control. If no serial flash operations are executed in u-boot I can access the flash in linux via mtd.
Kernel and u-boot are both current git HEAD with minor changes. Anyone with an idea?
Regards Matthias

Hi Matthias,

With some wild guessing I found out that it must be an interrupt issue. If I clear FR (offset 0x160) in the QSPI module using u-boot command Linux boots successfully. So it seams that u-boot should clear the interrupt flag of the QSPI module after it was used.
Or the Linux driver should take care of clearing this before enabling the interrupts instead. In general Linux should make no assumption of the previously used/configured devices.
Thanks, Stefan
Hi Stefan
Actually the interrupt flags are cleared in the driver found in the linux tree from freescale before the interrupts are enabled
/* enable the interrupt */ writel(0xffffffff, q->iobase + QUADSPI_FR); writel(QUADSPI_RSER_TFIE, q->iobase + QUADSPI_RSER);
Clearing of the flags is missing in the mainline driver. After adding the clear mainline kernel boots with an unmodified u-boot. So, I think I currently use a patched kernel until the change arrives in mainline.
Thanks to all Matthias
