AM1705, U-boot and NAND

Pavel Gorbokonenko

Other Parts Discussed in Thread: AM1705

Hello. I am use custom board based on AM1705. When i compiling U-boot with defination CONFIG_USE_ NAND (da830_evm.h), then U-boot loading but don't launching (not answer when i hit enter in HyperTerminal). When compiling u-boot with undef CONFIG_USE_ NAND, then U-boot launching and work. When i defintation CONFIG_USE_SPIFLASH, U-boot work too. What i can doing for work with NAND from U-boot (write, erase etc.)?

I am using DaVinci SDK 3.20....14, AISGen GUI and UartBoot Host. In AISGen boot mode select as UART2, configuration for console on UART2 too.

Pavel,

You may need to remove support for NOR flash when trying to add support for NAND. I would expect this would require undef'ing or commenting part of the config header file, but I don't have it in front of me, so I'm not sure. Also, as you are moving to a custom platform, do not be surprised to discover that u-boot will have to be customized to get it to work correctly (though the fact that the SPI version works may mean that changes will be minimal).

This link refers to CONFIG_SYS_USE_NAND in the config file. Is that the #define you are changing?

Regards, Daniel

Ii'm did this. My variant of configuration file in link below. In default variant NOR flash and NAND didnt using, using only SPI Flash.

Yes, that is. I'm tried differing variants: CONFIG_SYS_USE_NAND (old version) and CONFIG_USE_NAND (because in conf. file checked exactly second variant). I'm found conf. file for HawkBoard, where use #define CONFIG_SYS_USE_NAND 1. I'm tried this variant too.

I don't see any issues with the configurations, so I would suppose that there is something different with your custom board that has caused the standard u-boot build for NAND to be incompatible. You are going to have to debug the u-boot code to figure out why it is not starting up as expected. That could mean stepping through the code using a debug environment like CCS.

Just to check, you have the NAND connected to the same chip select as the other platforms (CS3)?

Regards, Daniel

Problem resolved. In my board NAND connected to the CS2 pin. I'm changed in config file pin to CS2 but forgot changed register to CF2.

Thank you, Daniel.

Pavel,

Good to hear. Please note that if you intend to boot directly from the NAND, that the device's ROM is hard-coded to expect the NAND connected to CS3, not CS2 (which is why the other platforms have it connected that way).

Regards, Daniel

New trouble with NAND. U-boot can read ID of NAND (0x75), erase command work without warning and show bad block. Read and write command work without warning or error, saveenv comannd work too. But when i check what was readed from NAND, i saw that all data is 0xFF. Used NAND of Samsung, 32 Mb, 8bit bus, 512 bit per page.

Whats wrong?

I change config only in da830evm.h file.
