Can any one provide ECC BCH 16-bits source code example?

Other Parts Discussed in Thread: AM3352

I am trying to bring up our AndroMeda with AM3352 and NAND detail as below:

NAND:

-Page size x8: 2176 bytes (2048 + 128 bytes

-Block size: 64 pages (128K + 8K bytes)

-Plane size: 2 planes x 1024 blocks per plane

-Device size: 2Gb: 2048 blocks

It can be loaded by booting from an SD card.

But when I tried to boot from Nand after writing XLDR, EBOOT and NK to Nand, it failed with a string of Cs out the serial port.

After some investigation I found that reason is the ECC type is not correct, we used ECC BCH 8bit, but it requires ECC BCH16bits, we only have source code with ECC BCH 8bit and 4bits.

So can anyone provide ECC BCH 16-bit source code?

Hi Andy,

I am not aware of the AndroMeda development platform. TI officially only supports the AM335x EVM, SK, ICE and beagleboneblack platforms for AM335x. I am not sure any of these platforms have a NAND with 16 bit BCH platform but for reference, you can refer to the code shared by E2E community member on the E2E post here as this feature is not supported in the TI RTOS SDK

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/241321/patch-for-16-bit-bch-ecc-in-starterware

Only other reference for 16 bit BCH ECC for NAND, will be part of our Linux/uboot NAND driver.

Regards,

Rahul
