Subject: [U-Boot-Users] Problem using cfi_flash driver for s29GL512N flashes
Date: Mon, 26 Nov 2007 20:46:21 -0800	[thread overview]
Message-ID: <18385083.518451196138781394.JavaMail.nabble@isper.nabble.com> (raw)


 Hi folks,
  
 Greetings everybody..I am using u-boot1.1.5 for at91rm9200ek type board(arm). The flash memory used here is s29GL512N(128k sectors).I am able to configure the board/config flle properly it seems. The driver also erases/writes properly it seems. The problem is when I am trying to save environment variables it is getting set but in some cases after a reset it is showing Bad CRC and getting to the default environment. The other thing is I am not able to boot the kernel image from the flash due to some bad checksum error. Everywhere the problem is related to crc. I am a bit confused why the CRC check fails everytime? Is it not writing properly and if it is not writing properly then how it is able to get the u-boot prompt..

The required configurations defined

#define CFG_ENV_ADDR (CFG_FLASH_BASE + 0x20000)
#define CFG_ENV_SIZE 0x2000
#define CFG_ENV_SECT_SIZE 0x20000
#define CFG_MALLOC_LEN (CFG_ENV_SIZE + 128*1024)
#define CONFIG_STACKSIZE (32 * 1024)

The TEXT_BASE in config.mk :

 TEXT_BASE 0x21F00000

 Please help as soon as possible...

 Thanks in advance and cheers
