[casper] Booting problem
Hello I set usbboot following this webpage: http://casper.berkeley.edu/wiki/Roach_getting_started of course, I save the changes to non-volatile flash: "saveenv" Now I meet a problem is I want to update the new version uImage-rmon-20090904. Due to saveenv for usbboot automatically, I can't type anything and ROACH has no interrupt booting process. How should I do to stop the automatic booting process and update the new version of uImage? Thanks. Regards C-H Cheng
Re: [casper] ROACH file copy failure (Laura Spitler)
Hello Laura I also had the same experience with this problem. The first, I assume you set all environment variables are OK. Then, you can change the documation path of libraries. For example, I set my path as "C:\casper\mlib_devel_10_1\... ". Previous setting is "C:\Program Files\MATLAB...", this setting will occur the problem for copying XPS_ROACH_base files.

[casper] PowerPC U-Boot Configuration
Hello I had erased/corrupted the flash memory during updating and I used OCD commander to program PPC's uboot over USBWiggler. Of course I had the macro(program.mac), too. I follow the web page: http://casper.berkeley.edu/wiki/ROACH_Bringup#PowerPC_U-Boot_Configuration When I execute the OCD commander with macro, OCD commander show me a lot of messages and the last line is "word 0x71000ffc = 0x4bfff004". Then, OCD commander stop working At the same time, I try to transfer uboot file to ROACH over serial port but no reponse. How could I do to complete the configuration? Regards C-H Cheng
Re: [casper] PowerPC U-Boot Configuration
Hello David I try the mac file http://casper.berkeley.edu/svn/trunk/roach/production/test_software/roach_testing/macraigor_macros/loadram_rinit_auto.mac it works. But the ROACH can't complete the whole uboot process. The screen only shows the message as follows: --- U-Boot 2008.10-svn2226 (Aug 7 2009 - 16:06:44) CPU: AMCC PowerPC 440EPx Rev.

Then, OCD commander stop working It looks like you have the correct macro - you would typically get that macro from the roach production files at: http://casper.berkeley.edu/svn/trunk/roach/production/test_software/roach_testing/macraigor_macros/loadram_rinit_auto.mac The final command that the macro runs is 'exit', which closes OCD commander. So OCD commander closing unexpected is a feature not a bug! Once OCD commander quits you should start seeing activity on the serial port. Wait a while (more than 10s I think) until a character starts repeating (it looks like an S in hyperterminal). When this happens you are ready to transfer. Use XMODEM (not YMODEM) to xfer the u-boot.bin file. You'll find the latest file in: http://casper.berkeley.edu/svn/trunk/roach/sw/binaries/uboot/ You should have uboot running after the xmodem transfer completes.

Also the telnet in ROACH setup OK and I can telnet to ROACH. (port 23, and 7147

Any idea?

[casper] Error in PhysDesignRules
Hello I use ISERDES to receive data over Black Box. Simulation in Simulink is OK. But while I generate the bof file over bee_xps, the error occurs! The error message is as follows: --- ERROR:PhysDesignRules:1242 - Invalid connection used for ISERDES. The ISERDES comp roach_iserdes_6bit_XSG_core_config/roach_iserdes_6bit_XSG_core_config/roach_i serdes_6bit_x0/iserdes_6bit/Iserdes_master D pin signal roach_iserdes_6bit_gpio_gateway is not driven from an IO. ERROR:Pack:1642 - Errors in physical DRC. --- I also find some information about this error. http://www.xilinx.com/support/answers/31620.htm Should I fix the UCF file? or other idea?

[casper] Error in PhysDesignRules
Hello I update the error information. While the output of ISERDES (build over Black Box) connects to shared bram of CASPER library, reinterpret, soft register of CASPER library and snap, the error still occurs. Only one situation the error disappears that is the output of ISERDES connects nothing or connects to scope over gateway out. This is very confused me! The simulation in Simulink is OK, but during generateing bof file, the error will occur at mapping stage. And I can get the error message: ERROR:PhysDesignRules:1242 - Invalid connection used for ISERDES. Also the error appears in the "input" of ISERDES. Any idea? Regards, C-H Cheng

Dear All, I want to use ISERDES in ROACH. I also use Black Box to impletement but there is error in mapping process during generating bof file. Any good idea? Regards, C-H CHeng
[casper] program ROACH over JTAG
Hello All If I want to simulate a design in ISE and generate a bit file to download to ROACH over JTAG. A problem I meet is the FPGA pin number assignment. For example, in ISE I select the device is vxs95t and the FPGA pin assignment in ucf file is according to my desing. But ROACH has a lot of FPGA pins which are not in my design but needed for ROACH, sys_clk_n, sys_clk_p, aux0_clk_p, aux_clk_n, ppc_irq_n, ...etc. Hence, I can't add these FPGA pins which ROACH is needed into the ucf file of my design. Otherwise, I will meet error in mapping process. How could I simulate my design and program ROACH over JTAG? Regards, C-H Cheng
Re: [casper] program ROACH over JTAG
Hello Suraj Thanks for you explanation. Maybe I don't describe clearly. I mean if I want program the FPAG on ROACH over JTAG. Also, the bit file is generated by Xilinx ISE not CASPER toolflow. In this moment, the ucf file of my design is only included the IO pins of my design. But a lot of pins that ROACH are needed are not included in my design. How could I program the FPGA of ROACH with my bit file? Thanks, C-H Cheng Hello, On Nov 3, 2009, at 6:39 PM, C-H Cheng wrote: Hello All If I want to simulate a design in ISE and generate a bit file to download to ROACH over JTAG. You can do this using the .bit generated by the CASPER toolflow, available in the same location as the .bof. bof files are generated from .bit files using the script 'mkbof' distributed in 'XPS_ROACH_BASE'. A problem I meet is the FPGA pin number assignment. For example, in ISE I select the device is vxs95t and the FPGA pin assignment in ucf file is according to my desing. But ROACH has a lot of FPGA pins which are not in my design but needed for ROACH, sys_clk_n, sys_clk_p, aux0_clk_p, aux_clk_n, ppc_irq_n, ...etc. Part of the magic of the toolflow is that it adds the necessary IO pins to the .ucf depending on which IO blocks you have selected to use (10gbe, adc, etc.). It's part of the reason that IO blocks get special designation as "yellowblocks", as they are processed differently for each block. Hence, I can't add these FPGA pins which ROACH is needed into the ucf file of my design. It would definitely be faster to just put the I/O blocks you want to use into a blank model file, and use the CASPER toolflow to generate the .ucf, by un-checking the boxes for 'update system design', 'system generator', and 'ISE/EDK/bitgen' in the 'bee_xps' dialog. This should take about a minute to complete. -Suraj
