After reset (POR, warm reset, or max reset), ARM program execution begins in ARM ROM at 0x0000: 8000, except when BTSEL[1:0] = 01, indicating AEMIF (AEMIF/OneNand) boot. See Section 3. 11. 1 for information on the boot selection pins. 3. 12. 1 Boot Modes Overview DM355's ARM ROM boot loader (RBL) executes when the BTSEL[1:0] pins indicate a condition other than the normal ARM EMIF boot. This mode is handled by hardware control and does not involve the ROM. In the case of OneNAND, the user is responsible for putting any necessary boot code in the OneNAND's boot page. After the AEMIF module is configured, booting will continue immediately after the OneNAND's boot page with the AEMIF module managing pages thereafter. · The RBL supports 3 distinct boot modes: ­ BTSEL[1:0] = 00 - ARM NAND/SPI Boot ­ BTSEL[1:0] = 10 - ARM MMC/SD Boot ­ BTSEL[1:0] = 11 - ARM UART Boot · In NAND mode if SPI boot fails, then NAND mode is tried. · RBL uses GIO61 to indicate boot status (can use to blink LED): ­ After reset, GIO61 is initially driven low (e. g LED off) ­ If NAND boot fails, then GIO61 shall toggle at 4Hz while MMC/SD boot is tried. ­ If MMC/SD boot fails, then GIO61 shall toggle at 4Hz while MMC/SD boot is retried. ­ If UART boot fails, then GIO61 shall toggle at 2Hz while UART boot is retried. ­ When boot is successful, just before program control is given to UBL, GIO61 is driven high (e. g. LED on) ­ DM355 Timer0 shall be used to accurately toggle GIO61 at 4Hz and 2Hz · ARM ROM Boot - SPI boot in NAND Mode ­ No support for a full firmware boot. Instead, copies a second stage User Boot Loader (UBL) from SPI to ARM Internal RAM (AIM) and transfers control to the user software. ­ Support for 16 and 24 bit SPI EEPROMs ­ Support for up to 30KB UBL (32KB - ~2KB for RBL stack) ­ RBL will copy UBL to ARM Internal RAM (AIM) via SPI interface from a SPI peripheral like SPI EEPROM. · ARM ROM Boot - NAND Mode (See Section 3. 12. 2 for a full explanation of the differences between Standard Mode and Compatibility Mode. ): ­ No support for a full firmware boot. Instead, copies a second stage User Boot Loader (UBL) from NAND flash to ARM internal RAM (AIM) and transfers control to the user-defined UBL. ­ Support for NAND with page sizes up to 8192 bytes in Standard Mode and 2048 bytes in Compatibility Mode Note: At the time of documentation for this device, 8192-byte devices were not available for testing. The code does contain support for these devices; however, it has not yet been tested. ­ Support for magic number error detection and retry (up to 24 times) when loading UBL ­ Support for up to 30KB UBL (32KB IRAM - ~2KB for RBL stack) Copyright © 2007­2010, Texas Instruments Incorporated Detailed Device Description Submit Documentation Feedback Product Folder Link(s): TMS320DM355 89 TMS320DM355 SPRS463G ­ SEPTEMBER 2007 ­ REVISED JUNE 2010 www. ti. com · · ­ Optional, user-selectable, support for use of DMA and I-cache during RBL execution (i. e. , while loading UBL) ­ Supports booting from 8-bit NAND devices (16-bit NAND devices are not supported) ­ Uses/Requires 4-bit HW ECC (NAND devices with ECC requirements 4 bits per 512 bytes are supported) ­ Supports NAND flash that requires chip select to stay low during the tR read time Notes: ­ See Section 3. 12. 2 for a full explanation of the differences between Standard Mode and Compatibility Mode. ­ The GIO000 pin must be held high during NAND boot for the boot process to fuction properly. Instead, copies a second stage User Boot Loader (UBL) from MMC/SD to ARM Internal RAM (AIM) and transfers control to the user software. ­ Support for MMC/SD Native protocol (MMC/SD SPI protocol is not supported) ­ Support for descriptor error detection and retry (up to 24 times) when loading UBL ­ Support for up to 30KB UBL (32KB - ~2KB for RBL stack) ARM ROM Boot - UART mode ­ No support for a full firmware boot.
