Release Notes for QNX Neutrino 6.4.0 BSP for Renesas SH7785 SDK 1.0.0#

System requirements#

Target system#

• QNX Neutrino RTOS 6.4.0
• Board version: renesas sdk7785 board
• 128M AMD / SPANSION MirrorBit flash
• 128M RAM

Host development system#

• QNX Momentics 6.4.0, one of the following host systems:
  • QNX Neutrino 6.4.0
  • Microsoft Windows Vista, XP SP2 or SP3, 2000 SP4
  • Linux Red Hat Enterprise Workstation 4 or 5, Red Hat Fedora Core 6 or 7, Ubuntu 6.0.6 LTS or 7, or SUSE 10
• Terminal emulation program (Qtalk, Momentics IDE Terminal, tip, HyperTerminal, etc.)
• RS-232 serial port
• NULL-modem serial cable
• Ethernet link

Getting Started#

Step 1: Connect your hardware#

• Connect the serial cable to the serial port of the Renesas SDK7785 and to a free serial port on the host machine (e.g. ser1 on a Neutrino host).

Step 2: Build the BSP#

• unzip the bsp package archive to the desired location on the host machine
• cd to the root of the BSP and type 'make'. The resulting OS image will be located in the images directory

Step 3: Transferring the Combined IPL / OS Image (e.g. ipl-ifs-sdk7785.bin) to flash#

• The OS image generated by this BSP will not boot when loaded by the ROM monitor shipped on the board. Therefore you'll need to first copy the combined IPL and OS image to the flash, then load and boot the OS image from flash, using the IPL. Alternatively the IPL can be used to serially download the OS image directly to memory, and execute it.

• STEP 1: Apply power to the SDK7785.
• STEP 2: The following should display in the serial console:

• STEP 4: Power down the target. Once the power is off, flip Dip Switch MISC_SW1 to OFF in order to boot from the flash bank B
• STEP 5: Reset the board and the IPL should now execute:
• STEP 6: Once the IPL is loaded, you will be given two choices:
  • Boot the image in flash.
  • Download the image serially.
• STEP 7: Press any key (other than d) to boot the OS image from flash.

Step 3 Alternate: Transferring the OS Image (e.g. ifs-sdk7785.bin) serially using the IPL#

Once the IPL is loaded on the board, the OS image can be downloaded serially as follows:
sendnto -b115200 -d/dev/ser1 ifs-sdk7785.bin

Once the transfer is complete, the OS image will be executed.
Note: The serial port may change, depending on which one is connected to the target. Please see the sendnto documentation in the Utilities Reference.

System Layout#

Depending on the position of the MISC_SW1 switch the flash base address 0x0 will point to one flash bank or the other:

Known issues for this BSP#

• Due to the use of an external clock, the serial driver must run at 115200 Baud.
• The documentation references the OS image and the combined IPL/OS image files respectively as ifs-sdk7785.bin and ipl-ifs-sdk7785.bin. These are the correct names when building the BSP from the command line. However when building the BSP from the IDE these names are renamed respectively to bsp-renesas-sdk7785.ifs and ipl-bsp-renesas-sdk7785.bin.
• The trigger levels for the devc-sersci driver listed in the QNX Momentics documentation are for the 7750, and have not been updated for the 7780, 7785. (Ref# 27945
  Workaround: Use the following trigger levels for the 7780 and 7785:
  • 64 byte tx/rx FIFO's
  • tx FIFO triggers: 0, 4, 16, 32
  • rx FIFO triggers: 1, 16, 32, 48
  • RTS triggers: 1, 8, 16, 32, 48, 54, 60, 63
• The OS image generated by this BSP will not boot when loaded by the ROM monitor shipped on the board.
  Workaround: Load and boot the OS image on the board using the IPL provided with this BSP. Refer to the BSP documentation for more details.
• On SH platform when 2 consecutive pipes are cascaded (using ksh), the second pipe doesn't appear to output anything, as seen in the following output:
