Hi,

I'm trying to do a simple hello world UART example using VSCode and PlatformIO. I have the Arty 35t board setup correctly with the E-Class bit file. I am running VSCode on Windows 10 and have the Shakti SDK installed.

When I try to run the Upload(either with the VSCode task or CLI), I run into an error with,

Error: failed read at 0x16, status=2
Error: failed write at 0x16, status=1
Error: failed write at 0x17, status=2
Error: Fatal: Failed to read MISA from hart 0.
Error: Target not examined yet

Any clues?

Also attaching full log here.

Hi @sathya281! Could you please describe (or ask someone who knows) how you debug your boards at the moment? What software, debug probe, target do you use (for example artix7_100t board)?

Hi,

Shakti platform has 3 new SoCs.

1. Pinaka - RV32IMAC - on Artix7 35T board
2. Parashu - RV32IMAC - on Artix7 100T board
3. Vajra - RV64IMACSU - on Artix7 100T board

We have updated created json files for each SoC.
We also have updated tool chain and openocd.
Kindly let me know how should I submit these changes to platformio/platform-shakti.

Thanks & Regards,
Anand

How can we submit documentation via ReadtheDocs? Is it by a PR filed through PlatfromIO-Docs repo ? or other ?

The built-in Hello World(via uart) example builds fine on Parashu and Pinaka but gives error on Vajra. I am using shakti framework v1.1.0 on Windows. Attached herewith (vscode)terminal pic-

Hello,

I am trying to upload a bitstream I have genrated with Chipyard to the ARty 35T using PIO, but when I try to execute the upload command the following error appears:

Error: no device found
Error: unable to open ftdi device with vid 0403, pid 6010, description '*', serial '*' at bus location '*'

*** [upload] Error 1

My pio.ini configuration file is as follows:

[env:artix7_35t]
platform = shakti
board = artix7_35t
upload_port = /dev/ttyUSB0
monitor_speed = 115200
board_build.bitstream_file = /path/to/my/bitstream

What could be happening?

Thank you very much in advance.
Best regards, MªJosé.

I get the following error while uploading hello world program to artix7_100t board

64 bit version of the riscv toolchain is used here.

The monitor_speed(baudrate) is 19200 not 115200 for shakti.

I have a doubt regarding the platform.ini. As part of the examples like hello program etc the values in platform.ini is static. How can i have my own custom platform.ini while creating a new project with the designated board? Do i have to add extra parameters to the board specification or other ?

Regarding the upload protocol statement for PIO , i have detailed the issue below.

Observation 1 : With "upload_protocol=custom" I am able to upload and debug well.

Debugging the Program

Observation 2 : Without "upload_protocol=custom" it doesn't upload.

What i feel is if we don't give the custom part, it tries to program flash instead.

I believe the crawler automatically updates the framework version in registry. In this case though there are no releases since the sdk is in active development and the platform json points to a commit hash "version": "0.0.0-alpha+sha.5880320115". I tried to include locally by changing to latest hash and using advanced installation but as expected it fails to find the sdk from registry. So how can I get the latest sdk ?
