Re: [U-Boot] [PATCH] ARM: mxs: Add mx28evk_auart_console target
Dear Marek I wonder, why dont you add support for the TQ SoM in the first place? I have plans to do it but I only have access to the board at work and I currently am very busy so have limited time testing the board setup, so I don't know when in time I will be able to submit such a patch. Regards Andreas ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
[U-Boot] [PATCH] ARM: mxs: Add mx28evk_auart_console target
The target uses AUART 3 instead of the DUART for console output.

Re: [U-Boot] [PATCH] ARM: mxs: Add mx28evk_auart_console target
Dear Otavio, Some boards don't have the DUART easily available (see STKa28 by TQ-group for instance) while a regular rs232 port is easily accessed. The purpose of this patch is more of a demonstration how to use the AUART driver and was requested by Fabio during the submission of the AUART driver.

Changes for v2:
- Added comment that regs-uartapp.h is pulled from LTIB
- BM_ prefixes removed and _MASK suffixes added instead
- BP_ prefixes removed and _OFFSET suffixes added instead
- BF_ defines removed altogether
- CONFIG_MXS_AUART_CLK renamed to MXS_AUART_CLK and guarding ifndef removed
- Added comments describing what is set and unset during init of driver
- Added newline that was accidently removed from serial.c
Changes for v3:
- All BV_ values are now on the form (value something)
- BV_ prefix removed and double underscore substituted with a single
- File comment of mxs_auart.c now attributes what the driver is based on
- Uses gd-baudrate instead of CONFIG_BAUDRATE
- If gd-baudrate is 0 it reverts back to CONFIG_BAUDRATE
- Checks the validity of the div value calculated when setting the baudrate
- Magic numbers are now defines instead
- Cleanup of comments
- Cleanup of commit message

[U-Boot] [RFC][PATCH] ARM: mxs: Added application UART driver
The driver is ported from a driver that was implemented
using u-boot 2009.
The driver makes it possible to use a regular application UART as

[U-Boot] [RFC][PATCH v2] ARM: mxs: Added application UART driver
The driver is ported from a driver that was implemented
using u-boot 2009.
The driver makes it possible to use a regular application UART as
the U-Boot output console for MXS CPUs.

---
Changes for v2:
- Added comment that regs-uartapp.h is pulled from LTIB
- BM_ prefixes removed and _MASK suffixes added instead
- BP_ prefixes removed and _OFFSET suffixes added instead
- BF_ defines removed altogether
- CONFIG_MXS_AUART_CLK renamed to MXS_AUART_CLK and guarding ifndef removed
- Added comments describing what is set and unset during init of driver
- Added newline that was accidently removed from serial.c

Re: [U-Boot] Implement AUART for i.MX28
Hi Sorry for not responding, work and vacation came in the way. No further work has been done, ill see if i can do some next week. Kind regards Andreas 3 aug 2013 kl. 20:35 skrev Marek Vasut ma...@denx.de: Hi Andreas, I have tried to implement an AUART driver for i.MX28. However for it to work I must print 1 character to the debug UART via the serial_pl01x driver. If I do this the AUART will start working. If I don't nothing will be printed to the AUART. Anybody can see any obvious errors? Signed-off-by: Andreas Wass andreas.w...@dalelven.com I have to wonder, is the AUART no standard UART IP ? Probably not as Linux also has a separate driver for this ... Lots of rambling follows below, but please dont be put off by it. Make sure to CC me and Fabio on the next submission. I can help you debugging the driver if you clean it up a bit. Bump, is there any progress here?
