AM4376: PROCESSOR-SDK-AM437X: NAND Bad Block error in u-boot

Part Number: AM4376

Tool/software:

Hello 

We have ISIS IS34M08G088-BLI  512MB in our custom board ,we are using U-Boot 2023.04-00001-gd63f266198-dirty (Oct 18 2024 - 13:33:40 +0530).

when we try to nand erase it give s bad block error on this chip. please find attached screenshot

Thanks

Mahesh
