According to the ANSI C standard, hosted * applications can rely on numerous system-services (including properly- * initialized device drivers and, in this case, STDOUT). * * When this program is compiled, code is added before main(), so that all * devices are properly-initialized and all system-services (e.g. the * library) are ready-to-use. In this hosted environment, all standard C * programs will run. * * A hosted application (like this example) does not need to concern itself * with initializing devices. As long as it only calls C Standard Library * functions, a hosted application can run "as if on a workstation." * * An application runs in a hosted environment if it declares the function * main(), which this application does. * * This software example requires a STDOUT component such as a UART or * JTAG UART, a CFI flash component, and 2 RAM components (one for running * the program, and one for testing) Therefore it can run on the following * hardware examples: * * Nios Development Board, Stratix II Edition: * - Standard (DMA RAM test will not run) * - Full Featured * * DSP Development Board, Stratix II Edition: * - Standard (DMA RAM test will not run) * - Full Featured * * Nios Development Board, Stratix Edition: * - Standard (DMA RAM test will not run) * - Full Featured * * Nios Development Board, Stratix Professional Edition: * - Standard (DMA RAM test will not run) * - Full Featured * * Nios Development Board, Cyclone Edition: * - Standard (DMA RAM test will not run) * - Full Featured * * Nios Development Board, Cyclone II Edition: * - Standard (DMA RAM test will not run) * - Full Featured * * Note: This example will not run on the Nios II Instruction Set Simulator * * Peripherals Exercised by SW ******************************* * The example's purpose is to test RAM and flash, as well as demonstrate the * use of the DMA controller and flash API in NiosII. * * The RAM test routine performs the following operations: * 1.) Tests the address and data lines for shorts and opens. * 2.) Tests byte and half-word access. * 3.) Tests every bit in the memory to store both '1' and '0'. * 4.) Tests DMA access to the memory. * * IMPORTANT: The RAM test is destructive to the contents of the RAM. For this * reason, you MUST assure that none of the software sections are located in * the RAM being tested. This requires that code, data, and exception * locations must all be in a memory seperate from the one being tested. * These locations can be adjusted in Nios II IDE and SOPC Builder. * * * The flash tests demonstrate the use of the flash programming API. After the * flash device specified is opened, the test routine searches for a block in * the device that is already erased. This prevents any overwriting of * important data that may be programmed in flash. When an erased block is * found, the routine performs a test of the flash API calls on that block. * * The following API functions are then run to test the flash interface: * * - alt_get_flash_info * This function queries the flash device and collects various information * about it. In the example, the results of this query are compared to what * is expected, and an error is reported in the event of a mismatch. * - alt_write_flash * This function writes a specified number of bytes to the flash device. * In the example, this function is called repeatedly in a loop to write a * lengthy amount of data. * - alt_read_flash * This function reads a specified number of bytes of data from the flash * device. In the example, alt_read_flash is used to read back and test * all of the writing routines. * - alt_erase_flash_block * This function performs a block erase on the flash device. * - alt_write_flash_block * This function writes an erase block of data to the flash device. * * During the test, status and error information is passed to the user via * printf's. * * Software Files ****************** * memtest.c - Main C file that contains all memory testing code in this * example. * **************************************************************************/
