Subject: [U-Boot-Users] Bug in StrataFlash drivers
Date: Thu, 10 Nov 2005 15:18:44 +0100 [thread overview]
Message-ID: <437356C4.9090704@dave-tech.it> (raw)
Several platforms are equipped with StrataFlash memory. Most of the
existing drivers seem to not handle correctly odd-sized buffers in
writing. IIUC the bug is the function flash_write_cfibuffer - enabled
when CFG_FLASH_USE_BUFFER_WRITE is defined - when working with 16-bit
wide memories. The following code ...
...
case FLASH_CFI_8BIT:
cnt = len;
break;
case FLASH_CFI_16BIT:
cnt = len >> 1;
break;
case FLASH_CFI_32BIT:
...
... must be changed like this:
...
break;
case FLASH_CFI_16BIT:
cnt = len >> 1;
if (len % 2)
cnt += 1;
break;
case FLASH_CFI_32BIT:
...
Best regards,
