  2 JTAG modules in pulpissimo
Posted by: nixie2002 - 10-22-2019, 08:19 AM - Forum: PULP General questions - Replies (2)

Hello.

In Pulpissimo, there are 2 JTAG modules - dmi_jtag, dm_top / jtag_tap_top & lint_jtag_wrap (pulp_soc.sv).

I guess dmi_jtag & dm_top are from RISC-V Debug Specification,
and jtag_tap_top & lint_jtag_wrap are sub-module of adv_dbg_if.

In Pulpino, zero-riscy core, whose registers are memory-mapped, uses adv_dbg_if as a debug module.
But ibex core at Pulpissimo follows the RISC-V Debug Specification and has no debug interface except one bit debug signal.


So, I don't know why lint_jtag_wrap still necessary in Pulpissimo.
(Any limitations for dm_top to access system bus ??)


Thanks.

Hello..
I have been trying to install PULPissimo and the GNU Compiler tool chain was  built successfully. in the PULP- Builder installation i have installed all the dependencies and the GVsoC build was built. But, in the "Runtime Build" process im facing an error for the command

  Query regarding PULPissimo Installation.
Posted by: shilpa_jay - 10-15-2019, 11:25 AM - Forum: PULP General questions - Replies (1)

Hello...
I'm Shilpa. As a part of my academic project I'm installing PULPissimo Platform for executing the RTL simulation. I found this platform very interesting and I was very keen to know about it in detail. But, during the installation process I'm facing certain errors which as a starter I'm unable to rectify. So, is there any basic procedures or guidance that can be provided.
Thank you

  Pulpissimo memory map generation.
Posted by: Akim - 10-08-2019, 11:52 AM - Forum: PULP General questions - Replies (1)

Hello,

We have been trying to understand how the Pulpissimo memory map is generated.
Our purpose is to add our own modules (ultra low power memory) to it and we would need to understand it.

We found that memories are defined in l2_ram_multi_bank.sv, but how to add new memory to it?

Please, can you clarify file names that need to be modified to change Pulpissimo memory map?

Br,
Akim

  Issues for pulp-sdk
Posted by: MarekPikula - 10-01-2019, 12:30 PM - Forum: PULP General questions - Replies (1)

I can see that there is no Issues panel in pulp-sdk project on GitHub. I have some things to discuss regarding Ibex integration and I guess it would be much better place for this than this forum. In my opinion reliable SDK is one of the most important parts of the entire system, so maybe it would be nice idea to enable it for others to easily file issues and ask questions?

  New SoC configuration for SDK
Posted by: MarekPikula - 10-01-2019, 09:19 AM - Forum: PULP General questions - No Replies

Hi, is there somewhere a guide how to create new SoC configuration for pulp-sdk? I'm basing on PULPissimo and just copied some files in `pulp-configs` to create custom configuration. I wonder though if there is some kind of recommended way of doing this and if there is some sort of documentation anywhere. I've seen different scripts (`pulp_chip_gen`, `pulp_soc_gen`, …), but there is no description which does what and in what scenarios one should be used.

  how to manipulating of GPIOs on Pulpissino platform
Posted by: mapletree - 09-23-2019, 02:46 PM - Forum: PULP General questions - Replies (3)

Hi,
I would like to do some manipulation of the user and general purchase I/Os of the pianissimo platform, for example to light up a user LED via pressing down a pushbutton.
I found the functions in the sdk runtime doc for configuring the gpio as a bus such as rt_gpio_init and rt_gpio_pin_configure etc, but I did not find any document mentioning the exact address/pin or registers that are corresponding to the LEDs or pushbuttons. I am wondering where to get the detailed info of such so that I can light up a user LED?

Thanks,
Mapletree

  how to compile and run an application for Pulpissinio on FPGA
Posted by: mapletree - 09-12-2019, 03:47 PM - Forum: PULP General questions - Replies (5)

Hi,
I have generated a Pulpissimo platform bitstream for Xilinx ZCU102 board. Now I am at the stage to compile a "hello world" example to try on the FPGA. I am having two problems here:

1. On the pulpissimo web page, after the instructions on how to create the .c file that includes the baudrate and frequency of the UART and the main() function, it gives instructions on how to compile an application by issuing " make clean all" command, but there is no corresponding Makefile, therefore, I got an error " No targets specified and no makefile found". I did all these in pulp-builder home directory. My questions are: a). is there an existing Makefile that I can borrow to compile my hello.c for RISCV?  b).  If I need to create my own Makefile, do I need to include the boot code? if so where to get the boot code (the same code in sim/boot directory)? It will be nice if there is an example Makefile that I can start with.

2. When I tried to connect to the JTAG interface on the board(JTAG pins are allocated on PMOD) by issuing the openocd command, I got an error saying "embeddedConfusedtartup.tcl:21:Error: Unknown target type riscv". The command I issued: $openocd -f openocd-zcu102-digilent-jtag-hs2.cfg. The screenshot of the error massage and the openocd config file are attached.


Please help!

Thanks,
Mapletree
