Mistral OMAP3530 Samsung memory

Please give me the details of the Samsung memory device?

Part Number(s).  POP or discrete?

Many NAND device details are contained in the flash tool config file.

For example need to know:

LPDDR: Size, bus-width, clk freq

NAND: Bus width? ONFI-compliant? If not, need to know:

bytes per page

spare bytes per page

pages per block

blocks per logical unit (device)

ECC requirements

Latest version of Flash Tool is available here.  Works with USB and UART.

Hi Michael,

The board is from mistral - OMAP3530 board# O3530-PB-1116, the memory is from Samsung - POP memory part# K5W1G1GACM-DL60, I tried to locate the datasheet with not too much success,

I have downloaded the new flashboot but the current parameters are for the Micron memory,

Many Thanks,

HR

HR:

I was able to find out that this is a OneNAND device.

Samsung Onenand K5W1G1GACM-DL60

Muxed OneNAND 128MB 1.8V 16-bit (0x30)

OneNAND version = 0x0221

WRITESIZE = 2048

Flash Tool does not support programming OneNAND flash.

This wiki article covers programming Samsung OneNAND flash using U-Boot.

Hi Michael,

OK, the issue is that I have set bootdelay=0 and I can't stop the program to get the U-bot prompt as the boot params are saved in the NAND, is there a way to erase the NAND using the Jtag?

Many Thanks,

HR

Hi,

     You can erase u-boot using kernel mtd utils command flash_eraseall and nandwrite.

      Hope this helps.

SriHarsha,

I can't get the U-boot prompt, Is there a Uboot version that run's the flash erase command, I need to erase only the boot params,

Thanks,

HR

Hi ,

        You may not need a u-boot prompt, you should be using the kernel mtd utils upon booting the kernel and getting the kernel prompt.

HR:

Do you have the option of changing boot mode switches and booting from SD card?

Hi,

If I remember correctly, with 03.00.01.06 release we did some basic testing with OneNand devices. You have to modify the code in order to enable OneNand support, in default u-boot configuration you have to do something -

diff --git a/include/configs/omap3_evm.h b/include/configs/omap3_evm.h
index 73a5c98..b0cec5f 100644
--- a/include/configs/omap3_evm.h
+++ b/include/configs/omap3_evm.h

 #define CONFIG_CMD_I2C         /* I2C serial bus support       */
 #define CONFIG_CMD_MMC         /* MMC support                  */
-#undef CONFIG_CMD_ONENAND      /* ONENAND support              */
-#define CONFIG_CMD_NAND                /* NAND support                 */
+#define CONFIG_CMD_ONENAND     /* ONENAND support              */
+//#define CONFIG_CMD_NAND              /* NAND support                 */
 #define CONFIG_CMD_DHCP
 #define CONFIG_CMD_PING

If you build the u-boot with above configuration, you should be able to use OneNand from u-boot prompt, just like NAND.
