Run the config script and choose your specific chip and demo board model. sigmastar sdk
If your app crashes immediately, check your bootargs . SigmaStar chips rely on reserved memory chunks (MMA). If your app requests more than what’s reserved in the bootloader, it will fail. # standard kernel makefile obj-m += custom_gpio
Optimized for GStreamer integration and hardware-accelerated encoding. If your app requests more than what’s reserved
// Map physical memory to virtual address gpio_base = ioremap(GPIO_BASE_ADDR, 0x100); if (!gpio_base) printk(KERN_ERR "custom_gpio: Failed to map memory\n"); return -ENOMEM;
The build process concludes by generating a flash_image.bin or a set of partition images (IPL, UBOOT, KERNEL, ROOTFS) to be burned via TFTP or USB. 5. Key Programming Concepts: The MI Layer
Before writing a single line of code, understand this hierarchy:
