Recover Omega2S+ from hard brick
-
Hi,
We are working with Omega2S+ and currently, the design process is going on so before completing the design works we need to know how to properly recover the Omega2S+ if it goes to hard brick by crashing uboot or by improper uboot. By referring to the documentation of Omega2S+ we got to know that there is a 32 MB SPI NOR flash in the omega2S+, so is there any way to recover the module from Hard brick by communicating with Flash through SPI
-
Can anybody please help with this issue?

@sajintricog How to programming the on board flash of an Omega2S(+) module with an SPI programmer
Connect
-
GND pins to GND
-
3.3V pins to 3.3V
-
HW_RST_N (pin 5) to
GND -
VDD_FLASH (pin 32) to 3.3V
-
SPI_CLK (pin 34), SPI_MISO (pin 35), SPI_MOSI (pin 36), SPI_CS_0 (pin 37) to the appropriate terminals of a programmer

Good luck!

Thank you so much for your reply, I have one more doubt about the same, whether we have to put the HW_RST_N (pin 5) to GND until the programming is done or we just need to put the same to GND only once?

@sajintricog You have to put the HW_RST_N pin to GND during the whole programming process and leave it open during normal operation.
