Also, failure modes for NAND flash and NOR flash, and test techniques that can find problems ahead of time Q: I’m having trouble booting from my S25 FL256 S device with my i. MX28 board. The error code that keeps recurring is 0x80501003, indicating that the file signature or file version is incorrect. Here’s my setup information: SPI NOR Flash: S25 FL256 S_64 K Linux BSP: - U- Boot version: u-boot-2009.08 Processor: i. MX281 Figure 1: i. MX28 PCB circuit with modifications Here are some additional details and steps I’ve taken: I added ss1, ss2 pins to spi pin desc struct (c file) After that, sf probe detected the Spansion flash device. sf probe 2:0 sf set_config_reg 0x04 sf erase 0x0 0x300000 sf write 0x x0 0x300000 The Linux boot stream image is written to flash, then I set the boot mode to 0010, but I’m getting the0x80501003 ROM error code. A. Thanks for your question. We’ve seen a number of similar queries so this deserves some discussion. Error code 0x80501003 does indeed tell you that the file signature or file version is incorrect. Below, I’ve outlined a series of steps that you can take to help resolve your problem. 1. You’ll want to install the U- Boot and kernel patches, for starters, and you can find them on the Spansion website here. There’s also a useful post called “ How To Enable SPI NOR boot for i. MX28” on the Freescale forum. 2. Download and review “i. MX28 Building Blocks,” which describes how to fully boot from Spansion's SPI flash. This slide deck shows the necessary hardware modifications that need to be completed on the i. MX28 EVK board before you attempt to boot using the FL129 P in quad I/ O mode. 3. You’re likely already familiar with the board details, programming, boot modes, etc., but it’s worthwhile downloading and reviewing the i. MX28 Applications Processor Reference Manual,l, especially if you run into other issues after following.

When operating M28 in 3,3 V or battery supply mode the PSWITCH signal is used to support different modes of operation, i.e. switch on/off, play, pause, etc. PSWITCH can be configured by software. M28 pin 222 is directly connected to the i. MX28 CPU. M28 Functional Block Pin PSWITCH222 When the PSWITCH pin voltage is higher than approximately 0,65 V for a time >100 ms, the DC- DC converter begins its startup routine. This is the primary method of starting the system through PSWITCH in 3,3 V operation. When using M28 with in this supply mode it must have a mechanism of bringing PSWITCH high to power up through an always-present supply (for example, battery or VDDXTAL). Usually the default U- Boot bootloader which is shipped with M28 takes care of all necessary presettings for the PSWITCH behavior. For more details for implementing dedicated functionality please refer to the i. MX28 Applications Processor Reference Manual by Freescale. A reset is applied to the M28 module by driving the reset input on pin 221 low for a minimum duration of 100ms. The reset line is implemented as open drain, pin 221 is directly connected to the i. MX28 CPU. M28 Functional Block Pin RESET221 M28 can be connected to different kind of supplies:a lithium ion accumulator which can also be charged by the module, supply range 2.6 V.4.24 V3.3 V, supply range 2.6 V.4.24 Va USB connection or generic 5 V supply, supply range 4.75 V.5.25 V Supply Mode Supply Voltage Supply Pins V Battery2.6 V.4.24 V.3 V2.6 V.4.24 V GNDGND1, 2, 13, 14, 23, 24, 35, 36, 45, 46, 55, 56, 65, 66, 75, 76, 85, 86, 95, 96, 105, 108, 112, 115, 116, 125, 126, 135, 136, 145, 146, 153, 154, 165, 166, 175, 176, 187, 188, 201, 202, 207, 208, 215, 216, 224, 229, 230 The M28 Evaluation Kit ( EVK) is the ideal solution for developing software on the i. MX28 application processor, making first steps on an unknown hardware.
