Questions frequently asked by our customers
- U-Boot tells me "Flash: ERROR: too many flash sectors". Why does this error occur?
- This error occurs if the flash chip that is mounted on the core module is larger that the flash size than can be addressed. We limit the flash sectors in the U-Boot configuration so that the correct size appears in commands (e.g. flinfo), but the real flash chip size is read out via CFI. You can simply ignore this error.
- U-Boot tells me "smc911x: Invalid chip endian 0x......". What's the matter?
- Your U-Boot binary supports an Ethernet chip from SMSC and it tries to detect one. Likely, you do not have connected an extension board containing this chip.
- While programming the flash with gnICE/gnICE+, the error "unknown error while programming" occurs. Is there a solution?
- Yes. For gnICE instructions, see GnIce. First attempt should be using the latest tool chain from 2009. (This does not work for BF518 and BF548). If this does not work, then use the second way described. You need the flash tool driver from VisualDSP++. Please select your core module on the main page, where you can find instructions how to get this driver.
