Flashing NetX 50 EEPROM
Hello,
I would like to try to update NetX 50 firmware using bootwizard.
My question is: Is SDRAM really needed? What if no SDRAM is connected in the SDRAM Interface of NetX 50? Would I still be able to flash EEPROM?
Also, after the SYS LED flashing step, why do I still need to connect the USB cable?
Thank you.
Best Regards,
Hi d0mbr1,
I just replaced netx50 with netx500...

The internal ram is "only" 128K. Most of it is used for the flasher binary. This is a program running on the netx which burns the bootimage into the flash. This means there is not much space left in the internal ram.
The flasher does not support streaming at the moment. The complete bootimage must be available somewhere in the netX memory. That's why SDRam is necessary to flash an image. It's used as a buffer for the bootimage during the flash process.
Are you using a Hilscher board or some custom design?
Also, after the SYS LED flashing step, why do I still need to connect the USB cable?
The sys led is just blinking and indicates that the rom code expects a connection on Uart0 or USB. You need to connect the USB cable to download the flasher binary and the bootimage from the PC to the netX.
The bootwizard comes with some documentation in the "doc" subdirectory. The "netXBootwizard.pdf" describes all steps in detail.
