TERES DIY Laptop / Re: 3D Printable Case for the Olimex TERES-I
« Last post by JC on June 22, 2018, 05:59:59 PM »
I'm creating a laptop enclosure in OpenSCAD right now. At the moment it is platform-agnostic and can scale based on how large you want the screen to be, how large of a keyboard you want, and other fitment parameters. It will be some time before I have a TERES-compatible configuration available or special mappings for specific keyboards, but it's all in the works.

JTAG / Example config file with ARM-USB-OCD-H and ARM-JTAG-SWD adapter?
« Last post by smithbone on June 21, 2018, 09:04:48 PM »
Anyone using this combination to do SWD successfully? 

I have board that does SWD only.  I currently use a JLink to program it but I'd like to use one of hte ARM-USB-OCD-H's we have.  I've got an ARM-JTAG-SWD adapter and I took my working openocd config file and changed the interface over to ARM-USB-OCD-H.  I then needed to set SWD_EN.  I've done so with:

ftdi_layout_signal SWD_EN -nalias nSRST

Our target config file connects to the system under reset with the following:

reset_config srst_only srst_nogate connect_assert_srst

It seems to talk to the adapter correctly  but fails to talk to the target.  Here's some of the openocd debug log with the failure code.

Debug: 247 93 command.c:143 script_debug(): command - ocd_transport ocd_transport init
Debug: 249 93 transport.c:239 handle_transport_init(): handle_transport_init
Debug: 250 93 core.c:643 swd_add_reset(): SRST line asserted
Debug: 251 93 ftdi.c:1225 ftdi_swd_switch_seq(): JTAG-to-SWD
Debug: 252 94 command.c:626 run_command(): Command failed with error code -4
User : 253 94 command.c:687 command_run_line(): in procedure 'program'
in procedure 'init' called at file "embedded:startup.tcl", line 495
in procedure 'ocd_bouncer'

The command in question is: program <file> verify reset exit

Anyone have an example of a working SWD setup with ARM-USB-OCD-H and ARM-JTAG-SWD?

TERES DIY Laptop / Re: Touchpad does not work anymore
« Last post by binutzu on June 21, 2018, 12:15:26 AM »
Just for the update.
The problem was the button board which i replaced with a new one. Old ribbon cables are still used although i ordered new ones as well.

@Olimex: thanks for the fast delivery.

Glad to have a fully working Teres laptop again  :)

I have the same problem

when you decompile the dtb

Code: [Select]
spi@48030000 {
compatible = "ti,omap4-mcspi";
#address-cells = <0x1>;
#size-cells = <0x0>;
reg = <0x48030000 0x400>;
interrupts = <0x41>;
ti,spi-num-cs = <0x2>;
ti,hwmods = "spi0";
clocks = <0xf>;
clock-names = "fck";
dmas = <0x15 0x10 0x15 0x11 0x15 0x12 0x15 0x13>;
dma-names = "tx0", "rx0", "tx1", "rx1";
status = "disabled";
};

spi@481a0000 {
compatible = "ti,omap4-mcspi";
#address-cells = <0x1>;
#size-cells = <0x0>;
reg = <0x481a0000 0x400>;
interrupts = <0x7d>;
ti,spi-num-cs = <0x2>;
ti,hwmods = "spi1";
clocks = <0xf>;
clock-names = "fck";
dmas = <0x15 0x2a 0x15 0x2b 0x15 0x2c 0x15 0x2d>;
dma-names = "tx0", "rx0", "tx1", "rx1";
status = "disabled";
};

TERES DIY Laptop / Re: phantom keys
« Last post by khumarahn on June 19, 2018, 11:05:29 PM »
But the battery connector has loads of pins, so it is not USB?

I removed the comma key, looked under it with a flashlight. Did not see anything suspicious.
