@LubOlimex Out of curiousity, does the size of the drive matter? Or can I use both 2.5 in, 3.5 in, etc. SATA drives?

I am getting these errors on my Olimex Lime 2 with the official Debian image. I just booted a fresh install, installed wireguard, and rebooted:

Any idea what the issue might be?

A20 / What is the difference between...

Last post by myrcy - October 19, 2024, 02:21:04 AM

Hello everyone,

Installing Debian unto my Lime 2 and am a bit confused as to which image to utilize.

The Debian website has these two images:
```
firmware.A20-OLinuXino-Lime2-eMMC.img.gz   2024-08-27 22:35    359K
firmware.A20-OLinuXino-Lime2.img.gz   2024-08-27 22:35    357K
```

What is the difference between them both? Which can I utilize with my A20-OLINUXINO-Lime2-E16GS16M-ND?

Thank you so much for any help.

What about an Xberry Pi or a Spectrum 128 clone ?

Thank you.

Last post by LubOlimex - October 18, 2024, 08:22:39 AM

Hardware has no limitation about the size of the disk. Linux is the limiting factor but the maximum size is a looot (more than the size any single SSD can be).

There are two things to consider about the SATA drive:

- Max speed is 1.5Gbps SATA, no point of paying for faster disks
- It should be 5V SATA disk (not 12V)

Also if you wish to power the driver directly from the board or you don't have adapter consider this set:

We also resell some hard disks and SSDs here:

A20 / Maximum SATA Drive size for Ol...

Last post by myrcy - October 18, 2024, 05:04:08 AM

Hello everyone,
    I hope this finds you well.
I was purchasing a SATA Drive for my Olimex Lime 2 when I realized that I am uncertain if there a maximum drive I can plug into the machine.

I know my USB reader only supports up to 4TB Drives. Is there a maximum for the Olimex Lime 2? Or can I plug in any drive?

Thank you so much for your help.

TI / Re: TMS328-XDS100V3

Last post by LubOlimex - October 17, 2024, 09:53:52 AM

Yes, pin 1 in ARM JTAG connector is for probing the voltage of the target, refer to this layout and focus on ARM-JTAG connector (right-most):

https://www.olimex.com/Products/DSP/Emulators/TMS320-XDS100-V3/resources/JTAG_connectors_XDS100.pdf

We have named it TVD - meaning Target Voltage Detect.

Last post by fi am - October 17, 2024, 12:21:39 AM

I read in the user manual: Works with targets in 1.65V-5.0V range
My question is how? I plan to use the ARM Jtag 20 pin connector.  Do I need to provide my vtarget voltage to pin 1?  For example if I plan to use STM32 powered with 1.8V do I need to provide 1.8 V to pin 1 of the 20 pin connector?

And if I plan to use anoter target, say it works with 3.3 V, do I need to provide 3.3 V to Pin 1 of the  20 pin connector?

Thanks.

Can anyone recommend effective libraries for managing power consumption on Arduino boards, especially for battery-powered applications?

Hi,
The STM32H407 work fine with micropython. But the GD doesn't. Usually I use a .dfu image of the firmware... Have I too, to try with the OCD and a hex format of firmware image?
Thanks.
