-# Analog Devices MAX32650/1/2
-
-This BSP is for working with the Analog Devices
-[MAX32650](https://www.analog.com/en/products/max32650.html),
-[MAX32651](https://www.analog.com/en/products/max32651.html) and
-[MAX32652](https://www.analog.com/en/products/max32652.html)
-microcontrollers.  The following boards are supported:
- * [MAX32650EVKIT](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32650-evkit.html)
- * [MAX32650FTHR](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32650fthr.html)
- * [MAX32651EVKIT](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32651-evkit.html) (Secure Bootloader)
-
-This part family leverages the Maxim Microcontrollers SDK (MSDK) for the device
-interfaces and hardware abstraction layers. This source code package is fetched
-as part of the get-deps script.
-
-The microcontrollers utilize the standard GNU ARM toolchain.  If this toolchain
-is not already available on your build machine, it can be installed by using the
-bundled MSDK installation.  Details on downloading and installing can be found
-in the [User's Guide](https://analogdevicesinc.github.io/msdk//USERGUIDE/).
-
-## Flashing
-
-### MAX32650 and MAX32652
-
-The default flashing behavior in this BSP for the MAX32650 and MAX32652 is to
-utilize JLink.  This can be done by running the `flash` or `flash-jlink` rule
-for Makefiles, or the `<target>-jlink` target for CMake.
-
-Both the Evaluation Kit and Feather boards are shipped with a CMSIS-DAP
-compatible debug probe. However, at the time of writing, the necessary flashing
-algorithms for OpenOCD have not yet been incorporated into the OpenOCD master
-branch.  To utilize the provided debug probes, please install the bundled MSDK
-package which includes the appropriate OpenOCD modifications.   To leverage this
-OpenOCD instance, run the `flash-msdk` Makefile rule, or `<target>-msdk` CMake
-target.
-
-### MAX32651
-
-The MAX32651 features an integrated secure bootloader which requires the
-application image be signed prior to flashing.  Both the Makefile and CMake
-scripts account for this signing automatically when building for the
-MAX32651EVKIT.
-
-To flash the signed image, the MSDK's OpenOCD variant must be used.  To flash
-the MAX32651EVKIT please install the bundled MSDK, and utilize the `flash-msdk`
-and `<target>-msdk` rule and target.

-# Analog Devices MAX32665/6
-
-This BSP is for working with the Analog Devices
-[MAX32665](https://www.analog.com/en/products/max32665.html) and
-[MAX32666](https://www.analog.com/en/products/max32666.html) microcontrollers.
-The following boards are supported:
- * [MAX32666EVKIT](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32666evkit.html)
- * [MAX32666FTHR](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32666fthr.html)
-
-
-This part family leverages the Maxim Microcontrollers SDK (MSDK) for the device
-interfaces and hardware abstraction layers. This source code package is fetched
-as part of the get-deps script.
-
-The microcontrollers utilize the standard GNU ARM toolchain.  If this toolchain
-is not already available on your build machine, it can be installed by using the
-bundled MSDK installation.  Details on downloading and installing can be found
-in the [User's Guide](https://analogdevicesinc.github.io/msdk//USERGUIDE/).
-
-## Flashing
-
-The default flashing behavior in this BSP is to utilize JLink.  This can be done
-by running the `flash` or `flash-jlink` rule for Makefiles, or the
-`<target>-jlink` target for CMake.
-
-Both the Evaluation Kit and Feather boards are shipped with a CMSIS-DAP
-compatible debug probe. However, at the time of writing, the necessary flashing
-algorithms for OpenOCD have not yet been incorporated into the OpenOCD master
-branch.  To utilize the provided debug probes, please install the bundled MSDK
-package which includes the appropriate OpenOCD modifications.   To leverage this
-OpenOCD instance, run the `flash-msdk` Makefile rule, or `<target>-msdk` CMake
-target.

-# Analog Devices MAX32690
-
-This BSP is for working with the Analog Devices
-[MAX32690](https://www.analog.com/en/products/max32690.html) microcontroller.
-The following boards are supported:
- * [MAX32690EVKIT](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32690evkit.html)
- * [AD-APARD32690-SL](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/ad-apard32690-sl.html)
-
-
-This part family leverages the Maxim Microcontrollers SDK (MSDK) for the device
-interfaces and hardware abstraction layers. This source code package is fetched
-as part of the get-deps script.
-
-The microcontroller utilizes the standard GNU ARM toolchain.  If this toolchain
-is not already available on your build machine, it can be installed by using the
-bundled MSDK installation.  Details on downloading and installing can be found
-in the [User's Guide](https://analogdevicesinc.github.io/msdk//USERGUIDE/).
-
-## Flashing
-
-The default flashing behavior in this BSP is to utilize JLink.  This can be done
-by running the `flash` or `flash-jlink` rule for Makefiles, or the
-`<target>-jlink` target for CMake.
-
-Both the Evaluation Kit and APARD boards are shipped with a CMSIS-DAP
-compatible debug probe. However, at the time of writing, the necessary flashing
-algorithms for OpenOCD have not yet been incorporated into the OpenOCD master
-branch.  To utilize the provided debug probes, please install the bundled MSDK
-package which includes the appropriate OpenOCD modifications.   To leverage this
-OpenOCD instance, run the `flash-msdk` Makefile rule, or `<target>-msdk` CMake
-target.

-# Analog Devices MAX78002
-
-This BSP is for working with the Analog Devices
-[MAX78002](https://www.analog.com/en/products/max78002.html) AI microcontroller.
-The following boards are supported:
- * [MAX78002EVKIT](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max78002evkit.html)
-
-This part family leverages the Maxim Microcontrollers SDK (MSDK) for the device
-interfaces and hardware abstraction layers. This source code package is fetched
-as part of the get-deps script.
-
-The microcontroller utilizes the standard GNU ARM toolchain.  If this toolchain
-is not already available on your build machine, it can be installed by using the
-bundled MSDK installation.  Details on downloading and installing can be found
-in the [User's Guide](https://analogdevicesinc.github.io/msdk//USERGUIDE/).
-
-## Flashing
-
-The default flashing behavior in this BSP is to utilize JLink.  This can be done
-by running the `flash` or `flash-jlink` rule for Makefiles, or the
-`<target>-jlink` target for CMake.
-
-The Evaluation Kit is shipped with a CMSIS-DAP compatible debug probe. However,
-at the time of writing, the necessary flashing algorithms for OpenOCD have not
-yet been incorporated into the OpenOCD master branch.  To utilize the provided
-debug probes, please install the bundled MSDK package which includes the
-appropriate OpenOCD modifications.   To leverage this OpenOCD instance, run the
-`flash-msdk` Makefile rule, or `<target>-msdk` CMake target.

+
+This part family leverages the Maxim Microcontrollers SDK (MSDK) for the device
+interfaces and hardware abstraction layers. This source code package is fetched
+as part of the get-deps script.
+
+The microcontroller utilizes the standard GNU ARM toolchain.  If this toolchain
+is not already available on your build machine, it can be installed by using the
+bundled MSDK installation.  Details on downloading and installing can be found
+in the [User's Guide](https://analogdevicesinc.github.io/msdk//USERGUIDE/).
+
+## Flashing
+
+The default flashing behavior in this BSP is to utilize JLink.  This can be done
+by running the `flash` or `flash-jlink` rule for Makefiles, or the
+`<target>-jlink` target for CMake.
+
+Most the Evaluation Kit and boards are shipped with a CMSIS-DAP
+compatible debug probe. However, at the time of writing, the necessary flashing
+algorithms for OpenOCD have not yet been incorporated into the OpenOCD master
+branch.  To utilize the provided debug probes, please install the bundled MSDK
+package which includes the appropriate OpenOCD modifications.   To leverage this
+OpenOCD instance, run the `flash-msdk` Makefile rule, or `<target>-openocd` CMake
+target.
