Subject: [PATCH 14/15] arc: libgloss: Add support of EM Starter Kit board
Date: Tue, 21 May 2024 10:56:57 +0100 [thread overview]
Message-ID: <20240521095658.10311-15-kolerov93@gmail.com> (raw)
In-Reply-To: <20240521095658.10311-1-kolerov93@gmail.com>
From: Yuriy Kolerov <kolerov93@gmail.com>
These specs files are introduced for EMSK board:
* emsk1_em4.specs - EMSKv1 with EM4 core, everything in
ICCM/DCCM memory
* emsk1_em6.specs - EMSKv1 with EM6 core, everything in
ICCM/DCCM memory
* emsk1_em6_ram.specs - EMSKv1 with EM6 core, startup code
in ICCM and everything else in RAM
* emsk2.1_em5d.specs - EMSKv2.1 with EM5D core, everything
in ICCM/DCCM memory
* emsk2.1_em7d.specs - EMSKv2.1 with EM7D core, everything
in ICCM/DCCM memory
* emsk2.1_em7d_ram.specs - EMSKv2.1 with EM7D core, startup
code in ICCM and everything else in RAM
* emsk2.2_em7d.specs - EMSKv2.2+ with EM7D core, everything
in ICCM/DCCM memory
* emsk2.2_em7d_ram.specs - EMSKv2.2+ with EM7D core, startup
code in ICCM and everything else in RAM
* emsk2.2_em9d.specs - EMSKv2.2+ with EM9D core, everything
in ICCM/DCCM memory
* emsk2.2_em9d_ram.specs - EMSKv2.2+ with EM9D core, startup
code in ICCM and everything else in RAM
* emsk2.2_em11d.specs - EMSKv2.2+ with EM11D core, everything
in ICCM/DCCM memory
* emsk2.2_em11d_ram.specs - EMSKv2.2+ with EM11D core, startup
code in ICCM and everything else in RAM
An example of building an application:
$ arc-elf32-gcc -mcpu=em -specs=emsk2.2_em11d_ram.specs main.c -o main
