| Booting Options |
| --------------- |
| |
| NB: The reference manual documents the RCW source with the *least-significant |
| bit first*. |
| |
| QSPI boot |
| ^^^^^^^^^ |
| |
| This is the default. ``{ SW5[0:8], SW4[0] }`` should be ``0010_0010_0``. |
| |
| SD boot and eMMC boot |
| ^^^^^^^^^^^^^^^^^^^^^ |
| |
| ``{ SW5[0:8], SW4[0] }`` should be ``0010_0000_0``. eMMC is selected only if |
| there is no SD card in the slot. |
| |
| .. _ls1046ardb_jtag: |
| |
| JTAG boot |
| ^^^^^^^^^ |
| |
| To recover a bricked board, or to perform initial programming, the ls1046 |
| supports using two hard-coded Reset Configuration Words (RCWs). Unfortunately, |
| this configuration disables most functionality, including the uarts and ethernet. |
| However, the SD/MMC and flash controllers are still functional. To get around |
| the lack of a serial console, we will use ARM semihosting instead. When |
| enabled, OpenOCD will interpret certain instructions as calls to the host |
| operating system. This allows U-Boot to use the console, read/write files, or |
| run arbitrary commands (!). |
| |
| When configuring U-Boot, ensure that ``CONFIG_SEMIHOSTING``, |
| ``CONFIG_SPL_SEMIHOSTING``, and ``CONFIG_SEMIHOSTING_SERIAL`` are enabled. |
| ``{ SW5[0:8], SW4[0] }`` should be ``0100_1111_0``. Additionally, ``SW4[7]`` |
| should be set to ``0``. Connect to the "console" USB connector on the front of |
| the enclosure. |
| |
| Create a new file called ``u-boot.tcl`` (or whatever you choose) with the |
| following contents:: |
| |
| # Load the configuration for the LS1046ARDB |
| source [find board/nxp_rdb-ls1046a.cfg] |
| # Initialize the scan chain |
| init |
| # Stop the processor |
| halt |
| # Enable semihosting |
| arm semihosting enable |
| # Load U-Boot SPL |
| load_image spl/u-boot-spl 0 elf |
| # Start executing SPL at the beginning of OCRAM |
| resume 0x10000000 |
| |
| Then, launch openocd like:: |
| |
| openocd -f u-boot.tcl |
| |
| You should see the U-boot SPL banner followed by the banner for U-Boot proper |
| in the output of openocd. The CMSIS-DAP adapter is slow, so this can take a |
| long time. If you don't see it, something has gone wrong. After a while, you |
| should see the prompt. You can load an image using semihosting by running:: |
| |
| => load hostfs - $loadaddr <name of file> |
| |
| Note that openocd's terminal is "cooked," so commands will only be sent to |
| U-Boot when you press enter, and all commands will be echoed twice. |
| Additionally, openocd will block when waiting for input, ignoring gdb, JTAG |
| events, and Ctrl-Cs. To make openocd process these events, just hit enter. |
| |
| Using an external JTAG adapter |
| """""""""""""""""""""""""""""" |
| |
| The CMSIS-DAP adapter can be rather slow. To speed up booting, use an external |
| JTAG adapter. The following examples assume you are using a J-Link, though any |
| adapter supported by OpenOCD will do. Ensure that ``SW4[7]`` is ``1``. Attach |
| your jtag adapter to J22. Modify ``u-boot.tcl`` and replace the first two lines |
| with the following:: |
| |
| # Load the J-Link configuration (or whatever your adapter is) |
| source [find interface/jlink.cfg] |
| # Use JTAG, since the J-Link also supports SWD |
| transport select jtag |
| # The reset pin resets the whole CPU |
| reset_config srst_only |
| # Load the LS1046A config |
| source [find target/ls1046a.cfg] |
| |
| You can proceed as normal through the rest of the steps above. I got a speedup |
| of around 100x by using a J-Link. |
| |
| Debug UART |
| ---------- |
| |
| To enable the debug UART, enable the following config options:: |
| |
| CONFIG_DEBUG_UART_NS16550=y |
| CONFIG_DEBUG_UART_BASE=0x21c0500 |
| CONFIG_DEBUG_UART_CLOCK=300000000 |
